A $99 PC obviously isn't going to deliver a blockbuster experience, but Shuttle's toaster-sized KPC actually has the hardware to get the lightweight job done: 1.8GHz Celeron processor, 512MB RAM and an 80GB hard drive, all of which is expandable. Overall, Tom's Hardware thought the cheap-o box delivered "surprisingly good" performance and value, except for the default OS Foresight Linux—its user-unfriendliness and bugs are the KPC's biggest problems. But, the Windows XP install "worked flawlessly" in case you've got an extra copy lying around and want a low-power mini-PC. [Tom's Hardware]
