I just updated all the way from Lion (10.8). It seems that every display has its own menu bar which I don't know if I like yet, but more disturbing to me is that one of my external monitors is flickering off for a second or two every minute or so after this upgrade. Not sure what the source of the issue is, but it was working fine before the upgrade. :/ I used to use a Matrox DualHead2Go DP Edition so I could use my two 19" monitors in addition to my main laptop screen. Earlier this year I bought a LandingZone docking bar which let me run one monitor via miniDV and the other via HDMI. This solution has worked pretty well so far, so I hope the flickering either magically fixes itself or that I'm able to find some cause and resolution. :) I need my three monitors. I've never liked the whole idea of virtual desktops, etc. and I like being able to see mail, calendar, shell, and browser just by glancing instead of requiring any sort of gesture or keystroke.
