I'm thinking that the computer/tablet space will be pushing resolutions much faster than the TV space. TV forever was in horrible 360i or something similar until HDTV came around and smacked it up to 1080p. Now you can get computer monitors capable of 1440p, Apple's iMac w/the bigger monitor even does 1440p for under $1,700 soon 2k and 4k will be rolling out. It does seem like tablets will be one of those driving forces that kicks up computer monitor resolutions. As mentioned earlier, it's not just the resolution its PPI, and the bigger the monitor the lower the PPI. When the tablet heads get used to the higher PPIs and become disappointed in their computer monitors they'll start demanding higher and higher resolutions. And likewise monitor manufacturers will need to start bumping up resolutions to keep up with the tablet space.
Good times all around, I'll probably go to 1440p or 2k fairly soon and likely drop off my monitor at work as they have me strapped to some shitty 19" ws dell. 19" ?? Puhleeaze.
Can't wait for 4k / 8k tho ! Virtual Reality here we come!
