when you just want to read a little bit or watch a movie then go for the nexus 7 or an amazon tablet/ebook.
if you are looking for a full spec high end tablet the nexus 10 would be a perfect choice or maybe the new sony tablet /samsung tablet.
for productivity an asus transformer, with the additional dock, is a charm.
anyway, the choices became so huge and the next gen tablet are already waiting behind the next corner...
funny fact, people are realising that the ipad isn't the only tablet on the market :D
