I'd wait now personally. the new Nexus tablets are sure to be hitting the market soon, meaning the current one is going to bomb in price.
Personally I think tablets are awful unless you don't have a pc/laptop handy.
Slow, clunky, not as easy to use, opening web pages is all over the place some load fine some the text is so small you then have to constantly zoom in after every click.
Media is the only thing they are good for, reading PDF's, watching videos or streaming (netflix/sky go).
I would only buy one if you plan on doing the above otherwise a laptop is the much better option. So many people have tablets which just sit there and get used once every 3 weeks.
