HowToGeek did a very nice article that breaks down how Windows RT (Windows 8 on ARM tablets) differs from Windows 8 on x86 (Intel chips). I expected there to be some differences, but didn't realize they would be THIS different! Wow! HTG Explains: What Is Windows RT & What Does It Mean To Me? The part that got me was the paragraph So Windows 8 on the tablet is going to be significantly different than that for desktop, laptops, servers and x86 (Intel)-based tablets!
