Everyone's favorite dominant ISP introduced an intriguing offer this week: Agree to use AOL for a year, and you can purchase a low-end PC from the company for just $299. Although the deal seems like a bid to stem the flow of subscribers eager to get out from under the multicolored, dumbed-down AOL interface, the offer actually appears to be decent, assuming you're not into playing the latest 3-D games. Of course, you can get a decent Dell system for not much more than the cost of the AOL PC plus the service (about $585 when you add it all up).
