All new. The 3 itself weighs similar to my iPad Air... a bit more with the keyboard, but it is far from the anti-terrorist clubbing weapon that the 2 combined with the battery keyboard is.

You get issued an external battery that is about the size of a sunglasses case. No crazy password required to log into the 3, too! You do a PIN like logging onto an iPhone or iPad. Talk about cutting down my muttering of a string of expletives the 4th time I fat fingered my password trying to log into the 2.
