How the original poster can say the current iMac is more attractive than any PC is beyond me - shoving everything into a big monitor is clever yes - but it comes at the expense of your monitor looking like a pizza box with a hole cut out of it.
At least with a PC, you sit the machine on the floor out of sight and all your left with is an ultrathin screen - better than an iMac every time.
I have wanted an iMac for a long time now - but no matter how many times I try and get used to it by starring at it in a shop or something, I know I can never work on something so hideously ugly and that is the single reason that has prevented me from buying one.
The thing is, there are many people - Mac users includes - who hate the fat plastic chin, and a lot of potential buyers who like me won't buy into something ugly -I can only expect sales to go through the roof once they finally remove it and come back with something more pleasing to the eye.
