Which tablet to buy ?

Tablets are at the top of many wish lists but which one to buy? The choice used to be pretty limited, with the iPad dominating the latecomers. But this year, the field is more even, as tablets from Apple's competitors have matured. In addition, Google and Microsoft are diving in with their own tablets, providing more choice. 

The first step in the buying process is to decide on the size of the tablet. They fall into two rough categories: the full-sized tablet, pioneered by the iPad, and the half-size tablet, epitomized by the Kindle Fire.
