Well, that was one option I mentioned because they are not cutting edge-- you can pick up one for a good price on eBay easily. The X201 series are indeed up to date, but Lenovo is currently sold out of the X201s model. Those would also be very good choices.
I love my x301 but I do agree.. it is out of date unfortunately. It was the perfect balance between the 12" and the 14" ThinkPads. My only gripe is that it's limited to 4GB. Anyone know if it's possible to exceed this limit?
A coworker of mine just got the T410s and I've gotta say I'm jealous. If I was buying a new laptop, I would go with the T410.
