I had a 4K 26 inch monitor and yes it was nice. But I travel too much and didn't enjoy moving it from place to place. Gave it to a good friend that I was visiting. Missed it for a little bit but quickly got used to using laptop screen. It is to the point that even if I'm in a hotel room with a large monitor/screen I usually don't bother to connect to it.

My point. Once you get better things yes it's easy to think you could never use the lesser tools you once had. But if the incentives are there, it's really not that difficult to adapt.
