I've actually really enjoyed the 3DS but unlike other Nintendo consoles it took me over 2 years to finally get one. Considering i tend to buy on release it was odd. However I would say that i am enjoying it more than the GBA or DS. I really loved those 2 but the 3DS has such polish to it, the games are awesome and last year was a great year for a handheld!
To be honest, if it wasnt for the 3DS my personal gaming habits ast year would have been dominated by FIFA
