Tomorrow, March 24th, is a busy busy day. Not only will we be seeing the official launch of the HTC HD2 and the Nokia Nuron, but T-Mobile has decided to add the custom Dell Inspiron Mini 10 with T-Mobile webConnect to the list. What a way to accompany the expansion of HSPA+! The Dell Mini 10 is your typical netbook, sporting a 10.1-inch WSVGA display, 1.3 megapixel webcam, three USB ports, VGA port, Windows 7 Starter Edition, a 1.66 GHz Atom N450 core and a claimed 8 hours of battery life. The difference? This one will have edge and quadband 3G (for all your roaming needs). It is available tomorrow for $199.99 on a two-year deal. Sounds great, right? Well, the bad news is that it will be limited to Chicago, Dallas, Miami, and Los Angeles retail stores, along with T-Mobile’s website and sales hotline. Leave your thoughts in the comments!
