I read somewhere that Pal Mickey is being discontinued, and that next year there will be no programming updates, and while the jokes and games will work, the park-based info will not. I believe this is because they're going to the Cell phone-based in-park info on the Verizon network starting next year.
I kind of wish I'd gotten one when they first came out, but I wouldn't spend $65 on one now when they're not going to be doing anything cool with them anymore in the parks.
