Check out this interesting but possibly bootleg phone made in the image of Astro Boy. The ATOM A520 looks like a toy, but is actually quite technologically advanced. It has cameras, bluetooth, a 1.5-inch screen, and can read MP3, MIDI, MP4, AVI, 3GP, JPG, GIF and TXT files.
I get the feeling that it's not an official product, but hey, points for trying.
This site is dedicated to everything Astro Boy, the works of Osamu Tezuka, and other related anime & manga. Whether you're an old-school fan, a newcomer, or anything in between, AstroBoy World is bound to offer something interesting for you.
