As I mentioned here, my camera is from the stone age and it's time for an upgrade. I put a new camera on my Christmas list, but I actually don't know anything about what's new and cool. I want to carry it with me in my purse, so it needs to be on the smaller side. I've heard these are good, but wanted to see if you had any recommendations for me. What camera do you use? What are the features that I can't live without? (Gabe, take notes).
