Perhaps as early as next year you will be able to run Windows on the same sort of low-energy ARM processors that iPads and phones use. Interesting.
What exactly is the point though? By itself, Windows for ARM doesn’t change a lot. All the programs that we use on Windows were written for Intel chips. They won’t run on ARM. They would have to be “ported” to the different architecture, and there’s no guarantee that a heavyweight program converted for a nimble processor would be anything you’d really want to use. Apple didn’t get where it is by simply porting Mac programs to the iPad. Garage Band, to take one example, is pretty much a wholly new version written to take full advantage of the touch interface.
It will be up to the market to create the software that really suits ARM-based Windows, and that of course depends on the platform taking off, which depends on the market… The Catch-22 of new technologies. Microsoft can seed it for success, but a huge amount of the detail still remains to be seen. It will surely run many Windows Phone 7 apps, but will it be able to take on the full-fat version of Office? (Rumours that it already can are probably based on an Intel tablet demo.) What about all the software created in Microsoft’s .NET framework? In Java?
Will it even have a desktop? This may seem an odd idea – Windows without a desktop? But in Windows 8, the desktop has been demoted to the status of an app; just another program, rather than an integral part of the operating system. Instead, the default interface of all Windows versions will be Metro, the “live tile”, highly touch-orientated look pioneered on Windows Phone 7. It’s all about fast and attractive access to information feeds. To do traditional work, with one or more heavy-duty application program running at once, you first open out a desktop. So it’s at least a possibility that the ARM-based version of Windows will only run lighter apps purposely designed for the touch interface. I am sure that “heavier” Intel versions of Windows will run those too though; Microsoft wants touch to be ubiquitous.
At the moment, leaving aside special-purpose and older versions, there are basically two Microsoft operating systems: Windows 7 and Windows Phone 7, and in most respects they’re distinct, incompatible things. In the near future though there could be a pretty continuous spectrum of Windows 8, over not two but four distinct types of device:
- Phones that can run lightweight touch-based apps.
- Light ARM-based tablets that can run the same apps – and some traditional software?
- Full Tablet PCs that definitely can run traditional software as well, but are still totally touch-orientated.
- Laptops and desktops that have an optional touch interface.
Hopefully they should all blend well so that data (and perhaps apps) move from one device to another seamlessly, even by touching them together. One can turn to the device suitable for your situation – a phone for walking, a desktop for work, a slate for sitting back – and find little changed about the user experience other than the size of the screen. It’s easy to see that merging very gracefully with “Surface“-type touch- and object-aware furniture. It’s as interesting as Windows has sounded for a very long time. Perhaps ever.
