No replaceable battery
= no sale.
I liked my old HTC Hero at the time, and would be prepared to go back to HTC, but not being able to change battery is a definite no-sale. I play some games that HAMMER it (gone in an hour) and being able to pop the back off and swap is a 'must-have', until batteries get 10x as long-lasting.
SD card slot is a 'nice to have' as well, but I can live without it.
