LCD Touch Screen "PDA"s for Kids?

John Q. Public asks: "I've seen the commercials on the usual children oriented channels this weekend, but I can find no technical data on the Mattel/Tyco Playtime/Fisher-Price Pixter, which investor and general press releases call a PDA for kids. It appears to have a 100x100 (or so) pixel 2 color touch-sensitive LCD 'with audio,' and accepts optional ROM packs for new functionality. I'd rush right out and buy one, but Amazon has the best price I've seen so far (US$40). Does anyone have any knowledge of these devices, specifically processor and 'ROM pack' details? Though I don't think I can pry the I Opener with the DOS based games away from my 3.5 year old, the Pixter might make road trips a bit more fun."
