Have the 05962RU version of the x120e (1.6GHz, Win7 Pro, 4GB, 320GB), love it. Keep the powerful desktop at the home office, but travel light. I use Windows Live Mesh to keep the two synced on the go.
As far as netbooks go, this is a workhorse of a netbook. If you want sexy or sleek or tons of bells and whistles, buy an HP. If you want a powerful, reliable machine for getting stuff done, get a Lenovo.
But yeah, 8GB RAM in a netbook indicates someone who doesn't know what they are doing. 4GB is more than adequate for anything you would want to throw at it, and 2GB is just fine for most basic tasks like web browsing and email.
