I've got two 20.5 inch Dell 2005's - love ' em - I prefer two monitors to one gianormous one because I can set my workspaces in Vegas accordingly - generally I have a workspace that utilizes both monitors however If I need to network between computers or hop online for stock media, I've got a layout that resorts to only one monitor while my second is used for other things, such as browsing, photoshop, after effects. To each his own however and how I would love a 30" Apple display but find the screen real estate of the two LCD's to be just perfect.
Do you find the "post" between the monitors an annoyance?
That would seem to be one advantage of one biggy, that is if you spread the timeline across both screens as I do.
I prefer the dual/triple head over 1 screen. The "post" as you mention - you just do not notice it after a very short time. (you can tuck one behind the other a little where they meet, and half the size of the post if it matters) The benefit about a second screen is using it as a dedicated preview device when you want, and also, should you desire you can use it as a magnified version of the other screen for close-up work. Also, you have redundancy if a screen goes, and 2 smaller screens are usually cheaper than a big 1. Also, the big ones don't seem to have such a high resolution without paying high money.

Sometimes.
To start, it was the little pop-up warnings/reminders that used to position themselves right there in the "post." I fixed that by massaging the software that came with the graphics card.
When I'm mixing a song, I like it spread across the two monitors. But then the cursor wants a spot right at the "post." So I've had to reduce the window width a little.
I wish for the ability to define what the computer calls the center. Short of that, though, things are not perfect, but still better than before.
Ah yes - forgot about that old centre screen behaviour - I just altered the properties to set focus to screen where my mose cursor currently resides - then it pops under in the centre of said screen. That solved that problem (sounds like you did too).
For me, when producing music, I have the track and song stuff on one screen, and mixer, vst, effects etc on other. I know it's all personal taste with everything, but then the cursor in centre is never an issue.
