Tablets are made to complement laptops, not replace them. If you're buying it to replace a laptop, you'll end up disappointed.
To answer the OP's question, there are 2 major contenders right now, iOS and Android. If you're a fan of iOS, the iPad will not disappoint. If you prefer Android, only go for Samsung. Since this does not seem like the thread for debating iOS vs Android, I'm not going to comment on the topic.
As far as Windows 8 tabs, their future remains to be seen. It looks great on paper though, but I'm not sure that the price point will be acceptable to the average buyer.
