My expirience (x201 Lenovo laptop) with external monitors is excellent. I use 'grandr' for setting up the VGA display and I'm used to work with the maximum resolution supported by the laptop (2048x1536) and works smoothly and fine.
Sleep mode and WiFi works natively too. I have had some problems with hibernate mode but I'm not using anyway. The only think you cannot use under Linux is the fingerprint reader. Everything else works like a charm.
