While the most eagerly awaited upgrade for the Lenovo ThinkPad X100e is arriving sometime in Q1 2010 (dual core AMD Athlon and Turion processors) Lenovo has added a third ThinkPad X100e model with Gobi 2000 3G and GPS where you can choose an AT&T SIM card or open SIM cards for either Verizon or Sprint. This model is priced at $649, which is $100 more than an identically specced model for $549, so this option is basically a $100 add on.
