ThinkPads are business oriented laptops.
The AMD Fusion E series CPUs are budget oriented and performs slower than an Intel i3 CPU. However, for simply office apps it should be fine unless you are trying to run some complex financial models in Excel or using a very large database.
I believe it uses the old Athlon II core, therefore, they are considered somewhat anemic compared to the Intel Core i3 CPU. That's part of the reason why the ThinkPad X120e series is so much less than the ThinkPad X220 series. It also starts with 2GB of RAM instead of 4GB.
