Thinkpad T420. I use it together with Unified Remote to watch movies or just general chill on the couch and consume some Internet stuff now. It also has a DVD player which is still very handy if you want to rent a movie from the (still existing) video stores or have bought a whole series as DVDs. It also automatically ejects any DVD before powering off using a poweroff hook.

Only thing that's missing is a remote power control so I don't have to unplug and plug it back in to power it on (lid is always closed). I was thinking about using Wake on LAN but so far I settled on a BIOS setting where the laptop is automatically powered on if it detects power.
