"On x86, Microsoft has given browser vendors the same privileges and APIs that IE uses. They have not done this on ARM."
Is it just me, or this an example of why Microsoft won't really be able to gain traction in the tablet market? When they first announced the versions, I looked at a comparison sheet between all of them and noticed one major thing, the ARM (tablet) version of Windows won't support the x86 (PC) version and vice versa. This makes sense. For example, nobody expects software written for an iPad to work on a Mac or a PC.
The difference here though, is that Microsoft is advertising it as a full blown OS will all the capabilities you'd expect from the PC version. But if they don't allow access to the same APIs, users might get really frustrated and won't understand why an app that works on their PC won't work on their tablet which is supposed to be the same.
Perhaps I'm wrong. Maybe Intel will release chips that gain traction in the tablet world, making this a non-issue. I'm guessing though, that once again, Microsoft is failing in their training/marketing department, regardless of how good or bad Windows 8 really is.
