axion axn6042The Axion AXN6042 portable DVD player may not have the biggest screen around (it's just 4.2 inches), but it does have a form factor that may make it attractive to DVD-toting travelers: the display is built into the lid of a player not much bigger than a standard portable CD player. Of course, it's still bulkier than most hard-drive portable video players, but in addition to the on-lid display, this player has a secret weapon that you won't find anywhere else: a built-in "Axi-Port" to connect it to Sega games (no, we don't get it either, but somebody must).
