This is the information I found on it. Dell Aero, one of the lightest multi-touch 3.5-inch Google Android-based Smartphone in the U.S., is designed to deliver a powerful, flexible, and entertaining experience in a stylish compact design. The Dell Aero is packed with today?s popular features including Quick Office, Facebook with integrated calendar and contacts, Twitter and additional applications by Google, including YouTube and Android Market.
Personaly I like it's sleek design, but let me know what you think!
If you're in the US and looking for an affordable Android phone on AT&T, I'd say the HTC Aria is better. It runs a newer version of Android and has a more common (and thus well supported by apps) resolution display.
