It depends. I almost never use my camera. Problem is, the launch dates for a lot of android phones are not set in stone, and we don't know if we will even get the nexus one officially. How soon do you need a new phone? I'm quite happy with my Hero.
EDIT: The htc bravo looks nice, but once again we don't know when SA will finally get it. Phones shipping with LED flashes (like the nexus one) are limited to close objects anyway.
Be very careful... I bought a Hero last year, but because of Leaf SA incompetency, is still stuck with the old ROM. They have promised updates for month, but have broken all of them. Every time I call, they have a different story.
