Well, the price was right, the system is nifty and fun, and I bought "Legend of Zelda: Phantom Hourglass" to play on it until I can hie me over to GameStop and pick up some Game Boy Advance cartridges like Tetris.
I have a Super Nintendo (bought new in 1994), a Playstation One (bought used in 2004), and now this thing.
The DS has no trouble hooking up to my WiFi network. Supposedly there's a browser for this thing out there somewhere--that would be neat.
Not being super-into video games, something like this is pretty much the extent of what I'm willing to spend on a game system. I still want a PS2 and DDR, though. Well, maybe next year or so. When Sony starts selling them for less than $130.
