After about four months of using a 5K monitor (in the form of a 27″ iMac), I can attest that it is simply stunningly amazing and everything I hoped it would be.
Whenever you can afford it if you use a monitor more than an hour a day, I recommend acquiring a 5K display. It makes a world of difference.
I don’t particularly care for Mac OS on the desktop but it doesn’t bother me too much. There is no Windows driver for 5K on the iMac, so that is not an option yet.
There is a Dell 5K monitor but it costs as much as the entire iMac which is itself a quite capable computer. In addition for the Dell variant you will have to buy a rather expensive video card to drive the thing.
When 5K gets cheaper overall I’ll probably switch back to Windows. But until then it’s the iMac for me.
Getting 5K is probably the best thing I’ve done in the computing space in a long time.
By the way, my iMac is indeed called “5KofGlory.”
