Could Samsung and Apple have another big competitor

For the past month or so, Samsung and Apple have dominated headlines with their patent trial. Such a case was probably inevitable – how many ways can you design a smartphone? – but any such case would inevitably gather daily headlines. After all, it was Apple and its iconic iPhone vs. Samsung and its status as world’s largest smartphone manufacturer. They’re both kings of the industry in their own ways. Yet they could have a competitor breathing down their necks before they know it.

Lenovo has been around for a while, and in their time they’ve made some waves in the laptop sector. Remember the IBM Thinkpad? In the late 90s and early 00s it seemed as though everyone had one. When IBM exited the consumer electronics business, they sold the brand to Lenovo, who have continued to the line to this day. They’re not quite as ubiquitous these days – the MacBook has taken over the role of the Thinkpad – but it’s still a high-quality Windows offering. In fact, it’s one of the main ways in which Lenovo competes with Apple.

The present: laptops

Let’s face it: laptops won’t be around forever. They’ve evolved to get smaller and smaller, but the latest round of laptops appears to be their evolutionary end. The only way to make them smaller is to remove the hinge, and when you remove the hinge from a laptop you don’t really have a laptop at all anymore. Still, the latest round of laptops, dubbed Ultrabooks, has made quite an impression on the market.

Apple started this trend years ago with the MacBook Air, but that model went through a few generations before it became a viable product. Once Apple got it down other companies followed. Lenovo got right on the trend, coming out with two lines: the ThinkPad, that business-class continuation of the IBM line, and the IdeaPad, a ligthweight, affordable Ultrabook meant for the consumer market. They are directly comparable to the MacBook Pro and the MacBook Air.

The difference, of course, comes in the price. The 13.3-inch IdeaPad runs more than $450 cheaper than the 13-inch MacBook Air, and more than $250 cheaper than the 11-inch MacBook Air. The ThinkPad compares even better to the MacBook Pro. The Apple faithful might not have much of a need for a different line of laptops, but the average consumer can benefit greatly here. Fact is, most people simply do not need a Mac. PCs can do pretty much the same, and oftentimes more. The saved dollars can go towards products of the future.

The future: tablets

To complete the thought above, when you remove the hinge from a laptop you don’t have a laptop. You have a tablet. While tablets aren’t quite to the level of replacing laptops, they’re certainly travelling that path. Just take a look at the super-thin keyboard cover for the Microsoft Surface. The writing is pretty much on the wall. Soon enough manufacturers will deliver laptops that make us look at laptops like clunky relics of the past.

In this territory, Apple is the undisputed king. People often ask me for advice on buying a tablet. They’ll ask, “is the new iPad worth it? Or should I get an Android tablet?” And I tell them that no, the new iPad isn’t really worth it; the iPad 2 is the second-best tablet on the market, and you can find it at a significant discount. Android tablets just aren’t there yet. But Lenovo has an idea.

First, they’ve put down the idea of competing with Apple on features. Samsung did this with the Galaxy Tab 10.1, pricing it at the same as the iPad. Seeing the two products next to each other, who was going to choose the Galaxy Tab? Lenovo has dipped below the iPad’s $500 base price. They’ve also differentiated, offering four different tablets: three Idea Tablets, ranging from 7 to 10.1 inches, and a ThinkPad tablet, designed for business.

Again, Android has a ways to go when it comes to tablets. But it appears that Lenovo has something going with its segmented offerings and skinned Android interfaces.

Smartphones in the offing?

It would be interesting to see if Lenovo decided to compete on all levels by offering a smartphone. It seems as though everyone’s doing it these days, and with AT&T and Verizon supposedly pushing customers away from the iPhone there might be an opening here. And again there’s a chance for Lenovo to segment its offerings, using Android for consumer and BlackBerry 10 for enterprise.

Yes, BlackBerry is something of an afterthought these days, but they do appear to have a strong offering with their BlackBerry 10 operating system. Problem is, they might need some licensing help to get it off the ground. Lenovo, which already has inroad to enterprise customers, could combine with RIM, which is – or at least was – the enterprise leader. On the other side, creating Android smartphones shouldn’t be such a big deal.

The Logo of BlackberryYet the competition issue comes into play here, too. Apple dominates its own little space, which consumes quite a large portion of the overall market. Samsung seemingly dominates the Android space. No one really dominates the Android tablet space, though, because it hardly exists. But if carriers really are pushing Android smartphones, there could be opportunity there.

Age of the smart consumer

I’d like to believe that we’ll soon enter the era of the smart consumer: one not dominated by fads and iconic brands, but rather by utility. The average consumer does not need a Mac, yet might feel as though they need one because everyone else has one. In truth, many other companies can fit the bill. Lenovo fits right in there.

And if you don’t need a product and can save money buying a comparable one, doesn’t that make the most sense? Wouldn’t it be more sensible to buy a $700 laptop and a $400 tablet for less than you’d spend on just a MacBook Air comparable to the other laptop? It makes sense to me.

How the USB revolutionised computing

This is a sponsored post. To find out more about sponsored content on Technology Bloggers, please visit our Privacy Policy.

The Universal Serial Bus, or as it is now commonly referred to as the USB, is a port designed to provide power supply or share data between electronic devices.

Ask someone to think about a USB, most people will naturally assume you are talking about a memory stick, which in essence is a super small, lightweight portable hard disk. However don’t confuse a USB port (the holding device) with a USB flash drive (a memory stick).

The USB (both port and flash drive) is something most of us take for granted in modern times, so I thought in this post it would be interesting to look at some of the uses for USBs, and how the USB has evolved over time.

USB 1.0

Design prototyping for the USB began when computing was still in its infancy, way back 18 years ago in 1994. At the time the port was being developed by the big players in the computing industry – Microsoft, Compaq, Intel, IBM, etc. These companies realised that there was (at the time) no easy medium which allowed communication through computers. For the computer to evolve, the companies realised that this would be an integral part of the system, as if you cannot share data, options are limited. Do remember this was happening in times before the internet was the global phenomenon it is today.

The first USB was produced in 1995 by Intel. Computers of the time started to come fitted with one or two USB 1.0 ports – although looking back, relatively few PCs were ever released with USB 1.0 ports. Nowadays, USB ports are in most cases a necessity for keyboard and mouse input devices.

The USB 1.0 was a revolutionary product, however looking back, its functionality was limited. Its maximum data transfer speed was 12 megabits per second. Relatively slow. That said, back when it was first introduced, a computers internal hard drive was typically only sized around 256/1024 mb (1/4 of a gigabyte to one gigabyte).

USB 2.0

In late 2000, the USB flash drive was released, enabling users to store more data than ever before, by storing things external to their computer. It would be an understatement to say that the USB flash drive was a step up from the floppy disk – it was more of a leap up! Initially, most USBs were typically 8 megabytes in size, meaning that they could hold more than five times what a floppy disk could.

Earlier in the year, the USB 2.0 was released, meaning that data transfer could happen 40 times faster, at 480 megabits per second. Initially some flash drives were designed for 1.0, however soon they were all being designed for the new 2.0 port, due to the increased possibilities.

USB 3.0

In 2008, the currently less well known USB 3.0 was released, which is more than ten times faster than its 2.0 brother.

USB flash drives have also improved over the years, and it is now possible to get a USB flash drive that is 256 gigabytes – one quarter of a terabyte. These disks are bigger than most computer hard drives were just a few years ago, showing the extent of the upgrades this technology has undergone.

A 256 gigabyte memory stick would though be useless with a USB 1.0 port as filling it would take almost 2 days (1.98 days) due to the speed of the data transfer. Even with a USB 2.0 port, the data transfer would take almost 72 minutes – more than an hour. Modern USB 3.0 ports could have the job done in less than 7 minutes. That really shows the true scale or achievement and advancement made in the USB industry.

Modern Uses

The USB is a crucial component of the modern PC, and is also very important for other devices. It is now possible to power many smartphones and multimedia devices via USB, either through a plug or your computer.

Some people use USB sticks to carry around a portable operating system with them, as it is perfectly possible to load Windows 7 onto a 16 gb memory stick and carry it around with you.

A USB penThe USB itself is a very flexible (not literally, the board would probably snap were you to bend it) device, with a lot of room for aesthetic variation. You can now get a range of Promotional USB Sticks, which many organisations often utilise, choosing to offer branded USBs as promotional gifts. This is all thanks to the readily available technology and cheap price of the components involved.

USBs now come shaped as credit cards, keys, pens, robots, people and even wine bottles!
