If your are using it as a monitor for development, web browsing and other standard desktop stuff the Seiki 32" 4k TV (only $350!) and a rMBP is great.

WRT the lag, etc. there's some minor screen tearing, but definitely no keyboard lag. It is necessary to turn off all the TV motion items and play with the colors a little but for the price it's great.

I switch between 30Hz and 60Hz displays, and the 30Hz always feels slow, including when typing. Probably depends on the person as to whether or not they notice it.

The smoothness of 60Hz is not to be underestimated.
