Perfectly - I implied that when I mentioned presentations, but I guess that wasn't clear. If you want only a second monitor, it's completely plug-and-play, with auto-detection.
I've only tried n = 2 monitors with this computer, which works, but in my experience with Linux, if you have any issues it'll be with going from 1->2, not 2->3 (or more). Ubuntu's had good support for this for a while.
This is entirely dependent on the video hardware. Some laptops video cards can support two external displays while the internal display is active and others cannot.
While the Intel HD 4000 supports 3 displays, according to the docs, it only supports them when used with series 7 chipsets and the specs on this ultrabook say it uses the QS67 which is a series 6 chipset.
