On the one hand I can't wait for 4k and high PPI mode adaption. Retina Macbooks already show just how pretty it is.

But the whole thing doesn't seem ready yet outside the Mac ecosystem. I see lots of issues with 4k:

- Going from 120 hz back to 60 hz, or even less. Seeing how they are struggling to get a 60hz monitor to the market, it's probably going to be a long time until we see 120 hz monitors.

- Software adaption for high PPI modes is going to take time.

- Games at 4k at 120 fps are going to be a problem for the GPU.

- Movies are going to be the biggest bandwidth hog ever, or ridden with compression artifacts.

So I'm not terribly exited yet. I probably still going to end up being an early adapter and eat through all these issues, but I think I'll wait at least one more year.
