Home Premium will suit most people. Heres what your missing out on not buying Ultimate
- Help protect against hardware failure
with advanced business backup features
- Business networking and Remote Desktop for easier connectivity
- Better protect your data against loss or theft with Windows BitLocker Drive Encryption
But the home basic is probably almost the same as XP, it doesn't have all there Eye Candy and stuffs in it... and the buisness doesn't really have much of the stuff you want at home.
...not really missing out of much eh? Unless your one of those people just want it because it's the best :)
