We've seen scads of portable NES mods in the past but still: this is probably relevant to your interests. ThinkGeek's got a new portable gaming system on offer, the Retro Mini Handheld. It plays all those 8-bit cartridges you've had stacked in your room next to your hi-fi since the olden days, and it's got a pretty attractive look. Sure, the cartridge is essentially bigger than the handheld itself, but that's part of its charm as far as we can tell. It's got a 2.4-inch LCD and takes four AA batteries for about 8 hours of game time, and it's available now for $49.99. There's one more shot after the break.
