Promptly following the launch its 13-inch ThinkPad Edge notebook, Lenovo has expanded the range with 14 and 15-inch models. The new machines are still aimed at small and medium businesses, and inherit most of their younger sibling's traits. It's worth noting that we recently reviewed the 13-inch ThinkPad Edge if you're looking for more information about the line.

Both new laptops start at $649 and are seemingly identical apart from display sizes. Each kicks off with an Intel Core i3-330M processor (upgradable to i5-430M) and built-in Intel HD graphics, 2GB of DDR3 1066MHz RAM (up to 4GB), a 250GB 5400RPM HDD (up to 320GB 7200RPM), a DVD burner, Wi-Fi, Bluetooth 2.1+EDR (on the more expensive models), a six-cell battery, and Windows 7 x64.

The systems also feature a seven-in-one card reader, an ExpressCard 34 slot, optional WWAN and GPS, a spill-resistant chiclet keyboard, and all the I/O ports you'd expect. All of the ThinkPad Edge notebooks are currently available through Lenovo's online store.
