The cheapest Inspiron Mini 9 netbook from Dell had a price of $349 in September 2008, but as of today you can get a black one for just $199! I'm not sure whether this is is a price cut or just a temporary deal, but if you're interested you can get one at Dell.
For less than $200 you're getting an Atom N270 1.6GHz system with a glossy 8.9" LED-backlit display with a 1024 x 600 pixel resolution. The Inspiron Mini 9 also has 512MB DDR2 memory, a 4GB SSD, Intel GMA 950 integrated graphics, 802.11b/g WiFi and a 4-cell battery. The operating system is Ubuntu Linux 8.04.1.
