if you wanna use your money as a social item to make yourself look rich to all your poor friends, buy an iPad
The main reason I would get an ipad is because literally all of my friends have one and they all enjoy them and I am pretty used to ios. With the surface I would have to get adjusted to windows 8 and the advantage there is running windows programs.
plus you have an entire keyboard lol (not sure if it has a numpad, i doubt it, but still.)
