Dell officially launched their Inspiron Mini 12 laptop today, the big brother of the Mini 9. You can choose between 3 different configs, or mod it to suit your own taste. Starting at $549 expect a 1.33Ghz Intel Atom Processor Z520, 1GB of DDR2 RAM, 40GB hard drive, WiFi G, Intel GMA 500, 3-cell battery and of course a 12.1-inch LCD. The Mini 12 is just under 1.1″ thick and weighs slightly less than 3lbs.

If’ you’ve got an extra $50 kicking around you can grab a slightly larger hard drive (60GB) and a battery twice the size.

You can pick up your very own Dell Mini 12 laptop here in black or white.  The system will ship on or before December 5th according to a Dell CSR.
