I have the 635 and I LOVE it. The only thing I wish it did better was close in on subjects. But, I think I would have to spend quite a bit $$ more to get the distance of a 35mm.
I did get a 256 memory card to get the most use out of the camera. It uploads quickly into my computer. I can alter the pictures before saving them. I like it. The ease of use is great and it is a nice size to carry around. I bought a Samsonite camera case at Walmart for less than $5 and it holds the memory cards, camera, lots of batteries, and I can wear it on my shoulder or through it in another bag.
The only thing mentionable is that the sucker eats batteries too, too quickly. I have a battery recharger and bought more batteries. At times, I have taken the batteries out of the camera for an amount of time just to keep them from depleting.
