TF700 has the slightly faster processor and of course better screen resolution. Fragmentation issues still exist (again rooting would help with some of that). The note has the S pen which is probably the game changer right there if you really put it to full use. Then there's the 2gb of memory for the Note as well. Of course you will have to sacrifice screen resolution. Other points would be TF700 feels much more premium than the plasticky feel on the Note. Asus also get its update faster than Samsung. I say other than Google's own product, Asus's products probably the fastest to get android update. There are however, lot of reports of QC issues on the TF700. Just read all the horror stories on amazon and other websites regarding all kind of QC issues Asus has with the screen.
Is there any way to root the TF700 without unlocking the bootloader/invalidating your warranty?
