Hello all. Just looking for some recommendations here.

What I will be using it for is mostly internet access, some office documents, and possibly a little virtualization. OS I plan on using is probably Arch linux. I currently have a netbook which is too small and too weak, and a 5 year old macbook pro which is large and only gets about 2.5/3hrs on battery.

So pretty much I want a middle ground system. I like the x220 from Lenovo. My preferred battery life would be around 5 or more hours. And the cost being kinda low would be nice (sub-600ish)...lower the better. So I am very open to used systems.

Let me know your input and suggestions. Thanks!
