The Nintendo DS's dual-screen design has always invited book comparisons, and the new DSi XL even more so with those two 4.2-inch displays, so now's as good a time as any for Nintendo to announce that its 100 Classic Book Collection will be coming to American shores on June 14 for $20. Joystiq says they're expecting the book list to be the same as the Euro pack, so expect some choice public domain works here -- we doubt this has got any of the big e-book players shaking in their shoes, but just wait until Miyamoto releases the $129 Wii Eye Motion Detector with packed-in Mario's Read Speed mini-game. Then it's gonna get crazy.
