Nintendo's new e-Reader uses what look like souped-up baseball cards—only these are loaded with everything from new Pokémon characters to the original low-tech version of Donkey Kong. Just insert the e-Reader into your Game Boy Advance, feed the cards through the slot to download the data, and you're good to go. Sorry, pink chewing gum is not included. E-READER, $39.95 at retail stores nationwide and on; game packs from $1.99.Robert Maniaci
