I don't normally post many deals on here but this one is a good one. If you're looking for a small, portable system then the Dell Mini 9 might be the system you are looking for. And until February 12th, you can pick one up for $249.
The $249 system is the Mini 9n, which comes equipped with an 1.6GHz Atom N270 CPU, 512MB of RAM and Ubuntu installed on a 4GB SSD. This price is a whopping $100 less than it was back in September, and there are no strings attached.
For an extra $50 you can get Windows XP installed on an 8GB SSD drive.
Hurry, the deal ends February 12th at 6am CT.
