I have been following forums on various Windows tablets since Windows 8 was announced and have questions on more technical aspects of the various device differences than what many posts cover when comparing devices. Perhaps a more technical person, which I'm not, can put the technical differences in plain English. I'm moving up from the Surface RT to a Windows 8 device and will be leaving my laptop behind as well. Can you explain why the 64 bit processor is used by Surface Pro rather than 32 bit used by other companies? Can you explain why Windows 8 Pro is used by Surface Pro rather than Windows 8? What I'm getting at is Microsoft decided on 64 bit and Windows 8 Pro for the Windows Surface Pro tablet for a reason, why other than ability to handle larger memory? I find myself always comparing other tablets running Windows 8 against the Surface Pro. Unfortunately I'm not up to speed on the technical aspects most consumers may not consider. Your input would be appreciated.
