Ok, my Mom isn't super tech savvy, but I would like to get her an iPod Touch for Mother's Day. I was planning on the 8 GB model (plenty for her projected use), but then I thought, would it be better to get her a clean used 3G iPhone? I would pull the SIM so she could still use it as a iPod, but the 3G iPhone would add a camera and GPS. I've seen some clean ones listed in the $200-$250 range. Which should I get? Other than being new and thinner, is there any other advantage that the iPod Touch would have over the 3G iPhone (w/o SIM)? Thanks!
