If you're the type to fear Windows 8 and seek solace in the arms of something older, you can always go left field and not only step back to Windows XP, but do it on a Nintendo console from the 1980s.
This wonderful bootleg does nothing more than emulate the Windows XP. The splash screen, password entry, desktop folders, there are even some basic programs like the calculator and games.
A copy just went for $US89 on eBay. Not bad, considering the novelty value!
