I think the major difference is that the Explorer can play videos and ebooks. I've also seen an attachment at Target to turn it into a camera and use the photos in learning games. My kids already have Leapsters, but if I were buying now I'd get the Leapster Explorer. Considering how much you invest in games, recharging battery packs, cases, etc. the extra money on the console is probably worth it for something that can do more.
