I went to #Re-PC yesterday (if you're not from the #Seattle area, it's essentially nerd thrift shop in a small warehouse packed to the brim with used/recycled electronics) and I saw this massive touchscreen display. I'd guess 7' x 3'-ish. They had a gameboy emulator up and I played some Tetris on it with touch controls.

You guys, I have absolutely no need for such a device, but I can't stop thinking about it. Thank goodness I don't have $500 to drop on some random nonsense, because if I had a ton of a disposable income, I might very well do it.
They also had a phat PS3 that I think had hardware back compat for PS2. It was $110 and I'm still kinda kicking myself for not snagging it even though I can't really afford that rn anyway.
