I'm not sure about win 8 RT, I kinda agree with the other posters that claim intel will make a processor faster that uses less pwr than Arm... To the others that claim windows 8 sucks... I agree that the first impression or while you are trying to figure this new OS... Things that helped me... 1. Setup with local account over Misrosoft account... I did not like all the syncing between the OS & a ms email address I don't uses much... I know you add others like gmail to your account, I still prefer the local account... 2. Uninstall all the apps you won't use.... Just cleans things up.... 3. Use the search feature to find ms you used in the past & pin to the start menu. After that I'm pretty happy with Win8... I'm using on a non-24'' monitor w/ a i5 based tower...
