Has anyone tried using the retina 5K iMac's screen using Screen Sharing over a Thunderbolt Bridge?

I have a macbook air and the only I was not buying a 5k iMac is that I like to use my laptop at work sometimes and would have to buy an extra monitor for it since the 5k iMac will not allow Targeted Display Mode.

Is Screen Sharing over Thunderbolt a good replacement for that? I mostly code and write documents..

I do use Screen Sharing over Thunderbolt Bridge, with a headless 2012 Mac mini.

You'll certainly notice some lag compared to Target Display Mode, but for those tasks it should work ok.

Screen Sharing has the added benefits of displaying in a nice window and sharing the iMac's keyboard and mouse, which I find more convenient than Target Display Mode.

If you want it to act like a true second screen (instead of simply mirroring your MacBook Air's 1440x900 display), you'll have to get an HDMI display emulator or app like Air Display.
