I don't know: can I use a thunderbolt port to chain monitors? About the dongles: in my use I usually take the laptop to the same places all the time, so I just buy the right cable (here it would be a thunderbolt -> hdmi cable i guess). If I go to random places where I need to hook up to a monitor I won't know whether they'll have a hdmi cable just as much as I don't know if they'll have a thunderbolt cable, so I need to carry a cable anyways. What's the difference whether it's a hdmi-hdmi or thunderbolt-hdmi cable? They're likely to have DVI or DP anyway, so you still need to take the dongles with you.
