My 19 year old Nintendo Gameboy! I found my old Gameboy (lifesaver during Desert Storm) while prepping for construction in my basement. Popped in some fresh double A's and viola! the haunting tones and geometric shapes of Tetris assailed my senses.
yeah last time I was home I saw my Gameboy and Gamegear. Gamegear was sooo much better...heck, Gameboy ripped off their design but it took another 10 years to do it!
