They're great as a small tablet, a client has bought a bunch for their staff to remote control their PC's while "at the pub" if there is an emergency call come in
The Note II's PPI is lower than the S3 (I couldn't go lower again!) and the CPU is the same, albeit clocked at 1.6Ghz as opposed to the S3's 1.4Ghz - which you can overclock if you so desire, but does it really need any more power?
I hope the S4 or S5 don't go ridiculously large on the screen front.
