You’ve Got Your Nice New Tablet…
Let’s put ourselves in the picture. When 2012 comes around, there are likely to be different versions of Windows 8 designed for different types of user, such as the home user, the work-place based professional user, etc.
There are likely to be high-end tablets similar to those that are currently available (it isn't uncommon to pay over $1000 for a Windows 7 tablet computer), hybrid devices (a notebook where the display swivels around to double as a tablet) and of course lower-spec tablets that will be available as an alternative to the iPad and Android slates that are currently enjoying a lot of success.
ARM is a set of instructions run by processors that are currently found in Android phones and tablets and the Apple iPad. These processors are cheaper to produce than those found in desktop and notebook computers (which use x86 instruction processor) and the method used to process data results in considerably less power being used. As such, this type of processor is perfectly suited to mobile devices.
The differences between ARM processors and x86 processors are numerous. Basically, the way in which each type of CPU deals with instructions is completely different - in layman's terms, the equivalent of relating a recipe in English to an Italian. ARM vs x86 Processors: What's the Difference? looks at this subject in more detail.
You'll find x86 processors in Windows desktops and notebooks, as well as Apple Mac computers; these are the "go-to" devices for data processing, whether for gaming, image and video editing, audio editing or programming and development.
What this means, however, is that software such as Windows Live, Microsoft Office and Windows games may not be available on ARM devices – legacy apps simply won’t run.
So what’s the point?
