We honestly didn't know what to expect from Wal-Mart's $200 Everex gPC, but it looks like the early results of putting Linux in front of Middle America are overwhelmingly positive -- Wal-Mart's online warehouse has already sold out of the cheapo Linux box, and users both savvy and new are filing enthusiastic reviews. Of course, it's still early and we can't imagine anyone getting too down on a $200 computer, but it certainly looks like Team Ubuntu is making a strong play to shift the balance in those OS wars.
