it is just a personal choice, you should go and try each of them out at like a sams club or someplace that has them both out.
Google is about to release a 10" tablet this coming week. I have an ipad2 from work and it is nice and handy to surf the web etc on. But if I had to buy one I would be interested in the new nexus
Also google just released a samsung chromebook which for like $249 is better than any sub $300 notebook you can buy. Great to just surf the web on, should be really fast
