HP has put plans to produce an Windows RT tablet based on an ARM processor on hold and is instead choosing to focus on Windows 8 tablets running on Intel’s X86 platform. According to HP, its customers have said that they prefer to have access to their legacy x86 apps, rather than be forced to buy new apps to run on the Windows RT platform.
Windows RT is likely to cause confusion in the marketplace because it looks exactly like Windows 8 on x86. The thing is that it’s not it is an entirely new mobile OS that requires all-new apps to be developed for it.
The advantage of having a mobile OS running on ARM is the devices are generally much lighter and have better battery life than those running on x86 and could compete with Apple’s iOS and Google’s Android tablets on a more even footing. But it won’t offer multi window multitasking and will be less robust then what you would get on X86.
Looks like Microsoft better watch out, you can’t go around pissing off your partners. It is rumored that HP was looking into ARM based tablets two weeks ago and after seeing Surface have scrapped these plans.
