I would say the pros are not there just yet; it would certainly look nicer, but not a whole lot nicer. Moving from 1366x768 on laptops to 2560x1560 (or whatever it is, can't remember off the top of my head) was a great shift. This isn't quite as big a deal. It would be very nice to be able to display full 4K detail or side-by-side 1080p videos for editing purposes. Photo editing will be great too, though you will have to resort to 'physical zoom' (i.e. moving your head closer) to do serious pixel peeping, rather than the old and probably superior technique of blowing up the pixels to larger than you'd see them normally. For gaming and such.... I'm not really sure. Downsampling is now the name of the game, i.e. rendering above the display rez and dropping it down, which has nice effects on IQ. Rendering 14.7 million pixels is a hell of a task to start with, and then you start getting all manner of masks, per-pixel effects, etc... the demands really multiply. Plus there's also a focus on high framerates, like 120, which we're not going to see at 4K or 5K for a gooood long while. It'll be years before things catch up at the mid-tier level of processors and GPUs. And 8 GB of RAM, I hardly need add, is entirely insufficient. tl;dr: for today's flat desktop purposes, probably not necessary but could be nice. for gaming and other purposes, probably reaching too far. but it's still a nice trend.
