I'll take the Dreamcast one, please
Wait, what? Not content with letting their mark on the hardware market fade into obscurity, Sega has teamed up with Japanese retailer Enterbrain to produce Sega flavored portable PCs.
This bizarre team-up has produced Mega Drive, Saturn, and Dreamcast colored machines, along with a general "Sega" themed piece of hardware. The specs for these machines can be found here.
I'm not a big fan of laptops or netbooks in general, but for the right price (right now they're going for ¥99,750 to ¥194,250), I'd easily pick up that Dreamcast one for pure novelty purposes.
