FWIW: I'd go for the TH-55, and buy a separate camera if higher resolution needed
The TH55 has more usabable RAM (32MB storage, compared to 16MB for the NX80 and 11MB for the NZ90), faster memory stick access, amazing battery life, newer operating system, WiFi built in, generally cheaper, ...
The only major things missing IMHO are a mega+ pixel camera and a CF slot.
The NZ90 and to a lesser extent the NX80 have much better cameras than the TH55 (640x480 CMOS), but if you want high quality photos a dedicated camera can't be beat.
If you absolutely need a CF slot for storage cards then the NX/NZ line is the way to go.
There are other minor things that may sway you to the NX/NZ (swappable battery on the NZ90, lame TV mode, music RMC etc), but IMHO they pale in comparison to the compact TH55 size and amazing battery life.
