I liked this phone and almost bought one off ebay (another story). The main issues with it as I see...
- Low-res screen (even compared to the 650)
- Motorola's locked bootloader and slow (or non) upgrades for MOTOBLUR phones
- Camera (fixed focus and so-so quality)
- Battery life (quite a few complaints)
- Reception (a few complaints)
Make no mistake, if you are not into gaming and you can accept the shortcomings, THIS PHONE IS A STEAL - Cause it has 512MB RAM and that's what it really counts for Android, all other low-end phones have only half of it.
And this little gem has CrystalTalk.
