Used it remotely, while also running a Skype screen share and voice chat to help someone do some web based work a while ago.
A little laggy, but was ok, complex webpages with lots of tick boxes and automatic refreshes were a bit of a pain, and they would see speeds slow down if they did a lot, but day to day it was fine.
If you want just simple web browsing, some video but not to the extent of downloading all of the Harry Potter movies via Sky (35GB I found out) then probably ok.
Would I buy it, only if I had no other option.
