Windows 8 RT (This is the name I believe it should be called) :
-Office Home and Student 2013 preinstalled WITHOUT needing to purchase it
-About 12,000 different devices support, basically, if the device was built from 2009 and on, it most likely will work right away, iDevices being the exception of course
-No viruses, malware, STDs of any kind
-Very good battery life
-Desktop File Explorer
-In the case of the Surface RT, touch or type covers along with a built in kickstand with dual 720p cameras
-Depending on the tablet, you can have 4G capabilities, like from att
-Xbox Music streaming, as well as neater designed apps!
-Ability of manage a Windows Phone with Windows RT as well as 8
-Through the use of BlueStacks, it appears that android apps will be able to work with Windows RT; also some Russian hacker/developer claims that he can get traditional Desktop software emulated on Windows RT, this has yet to be seen
-Unlike android or ios, Windows RT IS NOT Windows Phone, blown up by a factor of four, cuts out the phone and SMS part, and calls it good
Android:
-More apps, but comes with some concern as google is FINALLY starting to address the malware issue with some apps in their store
-Some phablets have USB support, SOME, not all
-Don't have a real file explorer
-When was the last time you plugged in your android smartphone into your android tablet? Oh yeah, never.
-May need to have an anti-virus/malware software installed to deal with security problems with android, as T-Mobile is ACTUALLY installing anti-malware software on android phones, PHONES!
-Can use other browsers
-Pretty much an android smartphone, blown up by a factor of four, cuts out the phone and SMS part, and calls it good
-From my personal use of android tablets, it ends up feeling bloated when you get an amount of apps installed, unless if it's android 4 but even then.
