I am typing this on a T420 although I just have 12gb not 16gb. No complaints. I like being able to swap the hard drives really quickly instead of messing with partition and the keyboard IMO is better then the new lenovo keyboards. If you are concerned about battery remember they are removable on the T420. In fact I often carry around an extra to double the battery life. I also on a Macbook Pro and frankly it is nicer in many ways but if you money strapped it probably isn't worth the price.
