I agree. I have a Dell Latitude E6420. With its all-metal case it feels even more sturdy than the Thinkpad T-series. Like most Thinkpads, the E6420 has is easy to disassemble and upgrade. Except for the fingerprint reader, everything works out of the box on Debian. The laptop also ships with a pre-installed Ubuntu. Acceptable keyboard and display, touchpad+trackpoint, optional built-in Smartcard/RFID reader, VGA and HDMI port. It is also very silent and cool most of the time. At first I was sad that I couldn't get a Thinkpad at work. However, after having spent one year with the E6420, I definitely prefer it over any Thinkpad and Macbook Pro I previously had.
