"Engadget has collected insider tips that Microsoft might have sacrificed backward compatibility with its “legacy” software (mostly of Windows 7 desktop variety) when shaping the design of Windows 8 for ARM tablets. This means that ARM tablets (and maybe netbooks based on ARM chips) will only sport a touch Metro user interface, and no fallback to full Windows “regular” desktop mode with its traditional keyboard and mouse support.
The significance of such a decision is hard to underestimate. Basically, it could means that legacy software developed for x86 architectures is suffering insurmountable difficulties in staying practical, or just plain working when recompiled for ARM architectures.
Even if Windows 8 core components and critical desktop software is completely re-written from scratch, it doesn’t guarantee that it will work flawlessly on ARM tablets.
First of all, in the ARM land there’s no single spec set of hardware to point at as a target for Microsoft developers. For Google’s Android, this disease is called “fragmentation”, losing control of the OS to OEMs is definitely not the Microsoft philosophy.
Second, whatever the single particular implementation will be chosen from (obviously) multicore Cortex A9 or Cortex A15-based ARMs, out of both current and future processors and SoCs, it’s clear that as of today they are all hardly powerful enough to be used and compete even with a low-end Wintel netbooks.
Just for the sake of illustration of difficulties in porting Windows 8 to ARM it should be noted that only two or three latest Cortex A15 prototypes mention support for DirectX technology.
Poor memory bandwidth could be another hurdle on the path of running Windows 8 on ARM tablet. In any case, a traditional, Windows7-looking legacy windowing system is just not that practical for a touch device, especially since its not optimized for touch-input anyway."
My dear imitator, just for once I am close to agreeing with you lol. It's not total garbage but it is very poor that MSFT can't be bothered to do the work to give ARM a working windows desktop mode or even Office 2012.
MSFT can do the port to ARM and probably already have a first pass done. They will proably segment the market so they can offer a lower priced Win8 for the "netbook class" & phone segments of the market.
MSFT is rich and generates substantial cash flow. That enables them to staff & fund projects that lean struggling companies cannot. That can be characterized as "fat" if you want to use that word.
"Lazy" is not a word that I would use to describe MSFT. What you are seeing on the outside of MSFT is the exposed part of their product plans that they want to disclose.
IMO, MSFT will probably release "featured" versions of Win8 that will be able to operate at different levels like: enterprise, workstation, home, .... MSFT is not responding to ARM but to Android. A competing Android OS with a large corporation behind it and a nice GUI is a direct competitor to MSFT. The first versions of Windows NT workstation that supported only TWO CPU could be converted into a many CPU Server version by changing a REGISTRY setting. MSFT quickly fixed that.
MSFT does not care about Intel CPU nor do they care about ARM CPU. MSFT will respond to the market to BOTH (#1.) protect their current legacy products and (#2.) to grow profits/revenue into the new markets.
MSFT is not going to get their traditional $119-$219 upgrades and full version pricing of $200-$300 in the phone/tablet markets.
