The 2560x1440 is QHD which is kind of a happy medium: high resolution enough to look really sharp, but not so high resolution that you have to scale it up like Macs do on retina displays. Having had retina Macs (and been very happy with them) since they came out, I've been using 16" and 17" QHD panels on my linux laptops for about five years... and they are actually just fine.
