I would much rather have lower prices than the "Free" 100gb on SD and Skype.
Paul, I hope you do a similar article regarding the convertibles: Sony, Lenovo, etc.
RT does run MS Office in desktop mode. Also IE so browser based educational apps will run (client server). Email on a large screen. RT would be good for many high school and college students...
