I have 2 Canon's-S50 and a Rebel XT 8MB DSLR. It really depends what you need the camera for. On most outings, I'll just throw the S50 (5MB) in the pack and I'm off. If I'm around the house or know I will be shooting a bunch, the XT goes. I like the compact nature of the S50 and it capures great images. I also had Sony cameras in the past. EVF cameras do have some advantages over DSLR models, in my opinion. Namely a strong optical zoom range/macro settings without having to swap out len's and they are more compact. The best camera in the world doesn't do you a bit of good if you don't have it with you when you need it.
The Sony were/are good camera's. I had the floppy Mavica,CD Mavica, F707, F717 and several point and shoot models in the past. Been eyeing the R1 recently but will wait for it to come down in price before I make a move on that model. The only beef I have with sony cameras is the color reproduction seems to be a bit on the "soft" side. I think the Canon's have much more vivid colors.
