Technology affects more and more areas of our lives. This area is to comment on contemporary IT issues. The views expressed are not necessarily those of Bluebird Software.  

Is the PC Dead?


Has the Personal Computer gone the way of the typewriter, valve radios and wind up gramophones? Companies such as IBM Hewlett Packard and Hewlett Packard seem to think so as IBM sold their PC division to Lenovo in 2005 and HP have just announced they are pulling out of manufacturing Desktops.

Steven Vaughan-Nicholls of Computerworld surmises that “The powerhouse of the computing revolution was born when IBM released the first IBM PC in August 1981. It died when Apple took the market lead from Microsoft.”
The mains powered PC now offers few advantages compared with a laptop or even a tablet. It used to be that CPU’s ran hot and you could only get adequate cooling by using large heat sinks and fans. Large hard discs were only available for PC’s.

Because of the heat and power problems, laptops had short battery lives, and could only use slow CPU’s. Now, because of fast, low power processors and high performance hard discs, not to mention long lasting lithium batteries, Laptops have similar performance ratings to PC’s and are now at similar or lower prices.

Other form factor computers such as Netbooks, Tablets and E-readers, not to mention smartphones are giving consumers what they want – Information wherever they happen to be.

Does this mean the PC is dead? I believe there are several important factors that will keep the PC market alive. In a business environment where PC’s are networked, information is often commercially sensitive and it is an advantage to have a system that is not portable. Another is spam and virus filtering so that with fixed PC's, IT managers can be certain that their systems cannot introduce viruses from outside.

To the enthusiast, a PC is easy to upgrade and repair, and to attach additional peripherals to. This is generally not the case with laptops which contain many more custom components. I think the PC will be with us for a few years yet, but, perhaps like line fixed line telephones, be a utility product that is out of the spotlight.

Zooming in on the Xoom

Xoom Tablet
It’s a pity Xoom isn’t a real word like Xerox has become. We Scrabble players could always do with more words beginning with X.

However the Xoom is Motorola’s latest Android based device. A tablet based on Android 3.0, (Honeycomb) Recently, I went to the Motorola App Summit in London and got a chance to play with one.
About the size of a slim paperback book, the Xoom will show videos, web pages, take photographs and HDMI videos with cameras at both front and rear, tell you where you are in space with GPS and of course, double as an e-reader. It is a very nice piece of kit, and if you paid cash for an unlocked model, would cost around £500. Pundits are not sure if it can compete successfully with the iPad which costs only slightly more.

There are several challenges developing applications for Smartphones and additional ones for tablets. For a Smartphone you have to consider that the user may have several applications open while taking a call, hopefully including yours and will want to be able to continue where he or she left off. You have memory use, battery drain and screen ‘real estate’ to consider as well as with a touch screen, the user controls must be well spaced and intuitive in design.

For Tablets, you can’t just port over a Smartphone Application and expect the user to be satisfied.

Small buttons scaled up from a Smartphone become enormous on a bigger screen, and graphics which look cool on a small screen look crude on a tablet. Then there is the question of soft keys. It was pointed out at the conference that many people hold a tablet with both hands, one at each edge and use their thumbs to type. This means that the keys should be at the left and right edges of the screen – not in the middle.

The Xoom has some advantages over the iPad. It works well with Flash as well as HTML5 which also allows videos to be integrated seamlessly into Web Pages and has a full Firefox Web Browser. One very interesting area is the possibility of writing a Webtop application. This is an application that uses web pages stored locally instead of being downloaded from a server. For the developer, this means being able to use well established web languages such as HTML and Javascript instead of a writing a Java App. However, Xoom’s hardware features such as the camera and GPRS do not currently appear to be available to apps designed like this.

So are tablets the way of the future – and has the Xoom got a future?
I keep thinking that some enterprising Taiwanese manufacturer will bring out a very low cost tablet which will make premium branded products irrelevant. This happened with the first PC’s. After IBM made their PC’s there were a large number of manufacturers making PC Compatibles, all using Windows 3.1.

The same thing could happen with Android. As Android is Open Source, there will not even be a licence fee to pay. I expect to see prices of Tablets plummet in the near future as these become almost commodity items.

The Key to Understanding

Typewiter I think it must have been the invention of the typewriter which gave us multiple functions for one key. If you pressed the shift button on the typewriter, you got capital letters - if you cancelled the shift key, you went back to small letters . A very neat solution which made the typewriter keyboard nearly half the size it could have been.

 We got the Hewlett Packard HP35 with two scientific functions to each key. Then we got the Sinclair ZX81 with four functions to every key. Micro-engineering was on its way…

Mobile phones allowed Nokia to compress over fifty two characters onto nine keys – but how far could this go?
We want pocket size products but with the ability to link seamlessly to our demands. Android phones now have Voice Recognition linked to Google search, so that if the phone only partly recognises what you say, Google will come up with a list of best matches – but is this the way forward ?

Only time will tell.
