Iv needed to get a new digital camera for quite a while now. My old powershot almost always gives me a "low battery" or "memory card error" message whenever I power it on. I have also been looking forward to 3GS prices dropping a bit on eBay so I can get one to replace my 3G. But now I'm thinking I might get the 3GS a bit sooner and just use it for all my picture-taking needs. Anyone else done the same without regretting it?
