AT&T announced today that it plans to expand its line of 3G-connected netbooks with the HP Mini 110. The carrier expects to begin shipping the Mini 110 on November 22, which will cost $199 after a mail-in rebate and signing a two-year contract. Plans will include a 200MB limit for $35 per month, or a hefty 5GB for $60, which is paired with free access to some 20,000 AT&T Wi-Fi hotspots in the US.

The HP Mini 110 features a 10.1" LED display, an Intel Atom processor, 1GB of RAM, a 160GB HDD, an HP webcam, an integrated microphone, and Windows 7. The system weighs in at 2.57lbs and will ship with HP QuickSync to automatically sync files with home or work PCs when connected to the same network. Also included is the AT&T Communication Manager (ACM) 7.0 which automatically connects the system to AT&T hotspots.

Of course, if mobile wireless connectivity isn't important to you, HP offers the Mini 110 for $300 through its online store.
