Traditionally computers have been tied down to one location, residing at home or in the office. However, with continuing advances in wireless connectivity the traditional computer market has become fractured and segmented into many new classes. This sits in parallel to the automotive industry where classes for cars, trucks, and their sport utility variants have existed for some time now.
For computers the range and breath of classes which exist is still relatively small. Moving from the most powerful to the most portable the picture looks something like this; Servers - Work Stations - Desktops - IMacs (all in one units) - Notebooks - Sub Notebooks - Full Tablets - Web Pads - IA's - Palm Tops - PDA's - WAP devices, and finally, embedded applications just to name a few.
Enter the Tablet PC, a full featured system running a Windows variant OS on ANY X86 capable low-power processor. That 'any' is the key word to make note of as "Microsoft expects all chip companies will produce great low-powered CPU's because it is convinced that this is the direction in which mainstream personal computing is headed ." While Transmeta may have had the honor of being the first processor to associate itself with the Tablet PC, Microsoft is by no means removing the prospect of competition for its mobile computing platform.
Not much on the detailed workings of the Tablet PC has been released, but we do know a few things. The device runs on the Windows OS, maintains wireless connectivity via 802.11 and Bluetooth, has a touch sensitive high resolution LCD display for use with with a stylus, uses a hard drive for storage, has at least 128MB of onboard memory, uses an advanced hand writing recognition application which leaves written entries in their original form, is light enough to be held in one hand and finally that it will not be using an embedded OS like Mobile Linux. While battery life is expected to be long, no specific times have been mentioned. Microsoft expects to have the OEM produced units to market in 2002, priced competitively with standard "full-function PC's."
Of all this, one thing is abundantly clear after reading the Microsoft Press Releases. Microsoft is desperately trying to persuade users from taking interest in the WebPad variant IA's. Citing the ability to use "full-strength" familiar Microsoft Software applications, no need for formatting or porting of data, full internet connectivity and the ability to open attachments from emails. Thus the Tablet PC seems to be less of an innovation and more of a Notebook with a formfactor facelift.
This notion brings up the question (as I suppose it was designed to) of what exactly so called WebPads offer and what the consumers preconceived expectations are for them. Are WebPads simply browsers with email functionality akin to WebTV? Or, are they simply operating on a hybrid OS while delivering most of the functionality of a normal notebook? Lastly and most importantly, what will consumers be satisfied with?
While Mobile Linux based WebPads are extremely promising, their apparent limitations will probably be surpassed with continued development. Meanwhile several other manufacturers have already begun to market their Tablet PC variations. Innolabs have already demo'd a full-feature tablet running on Crusoe with Windows 2000. It appears that this level of functionality is the most promising for the consumer right now. The browser and email-only platform is simply too limited by the internet itself.
Were software applications that are currently only available as installed programs widely accessible from the Internet itself the situation would take on a different light. Were the browser to be the interface to access Word or AutoCAD residing on a NET-based 'application server' the tables would be sharply turned in favor of the Mobile Linux environment.
