I'm little more than an amateur photog, but i agree that the camera is sorely underrepresented. I bought vignette, but i'm becoming increasingly disappointed in it. I don't so much value perfect color reproduction (this is a phone, after all) as i do being able to quickly take a clear picture, when i want to. Otherwise the convenience of having a relatively capable camera on you at all times is for naught. Vignette is novel, but little else. If you're a very art-sy photographer, it may have value. i am not. I take random pics of things i find interesting at random times, (in class, etc) and a silent shutter and focus was something i was seeking. Vignette also has some valuable timing functions, a baffling omission from the stock camera. i'm running 2.1 btw, hopefully only until later this week. Camera360 goes berserk on my X, and it refuses to reference the froyo gallery instead of the eclair gallery.
edit2: i did just discover though that having my phone set to silent silences all stock camera sounds. duur.
