Exactly. the n9 has front facing cam, and NFC and 1gb ram and is pentaband AND it has support for even WIFI a, unlike the 800. The 800 lacks all these. I'm partial to the 710 though, it has physical buttons and it's cheap, and has micro SD card support up to 32 GB yay (according to the specs at least). Removable battery too it seems. Kinda dissapointed in the 800 tbh, I would get the n9 instead.

Comparing the 800 to the n9, the only thing that is better about the 800 (disregarding OS) is the processor, everything else the n9 is better overall.
