I fully respect the fact that you find the iMac ugly. But you're definitely in a tiny minority, for most people who are ready to see it change still don't find it "ugly."
The iMac design was great when it was first released. There wasn't anything else like it. I've owned the aluminum 24", 21.5", and 27" over the years. But it is no longer attractive when compared to other displays. (I also had a purple iMac way way back, haha.)
Of course there are those who will purchase an iMac regardless of looks because they have an immediate need for one, but I'd argue that it isn't possible to look at an iMac and not feel that it is a dated design. (It's been what, almost 10 years since the current iMac design was released, with some minimal changes since?) Apple knows that, and the design will be updated eventually.
I am in a minority of purchasers because I am platform agnostic. I can do my work on any platform, but I've been a Mac user since the 90s and would like to have access to both platforms on the same hardware. The only thing that would bring me back to iMac would be a new design. I have a 4k monitor now but I'd really like to have a 5k iMac. Fingers crossed Apple launches a redesign sooner rather than later.
[doublepost=1527135992][/doublepost]And I want to add -- I say all of this as someone who used to be a huge Apple fan. I was a Mac guy for a long time. I've been to Macworld just to see Steve Jobs deliver the keynote in person. I've had everything Apple makes -- laptops, desktops, monitors, phones. I used to be a very passionate Apple fan and watched every keynote, salivating over the latest specs that I just had to have. So it actually feels very frustrating to me that Apple hasn't released anything new and exciting on the desktop Mac front for many years.
I want to be excited by a desktop Mac again not because of specs, but because the hardware looks freaking amazing. Apple used to be the only company that could make a new desktop that I'd immediately want to spend money on. I've had it all -- MacBooks, iBooks, G3/G4/G5/Pro towers, Mac Minis, iMacs.
I don't think I'm being unfair when I state that the current design of the iMac isn't just uninspiring -- it's a step down from anything offered by the competition. Apple can and will do better. It's just frustrating waiting for it.
