The same goes for the height and weight ranges that Microsoft provides: Windows RT tablets will weigh between 1.15 pounds and 2.64 pounds, and measure between 0.33 inches and 0.62 inches thick, but Microsoft own x86-based Surface Pro tablet will also fall within those measurements. Until we get more specifics on hardware, it's too early to say whether all Windows RT tablets will have better battery life and slimmer profiles than all Windows 8 tablets.

I did find this one tidbit from Microsoft's blog post rather interesting, though (emphasis mine): "Windows RT software will not be sold or distributed independent of a new Windows RT PC, just as you would expect from a consumer electronics device that relies on unique and integrated pairings of hardware and software. Over the useful lifetime of the PC, the provided software will be serviced and improved."

This suggests that, at least for Windows RT, Microsoft will offer more frequent software updates, perhaps mimicking the yearly update cycle of Apple's iOS and Google's Android. That would make sense if Microsoft wants to with its competitors' software innovations, but it also raises questions about how frequently Microsoft will offer updates for x86-based machines.

Unfortunately, Microsoft's blog post doesn't answer the : How much will Windows RT tablets cost? Give it a month, or two at the most, and we'll finally get an answer.
