Not any, no, but the Dell is. To me, I see the Dell's characteristics as 98% the same as the iMac, but then again I am a product designer so I see and analyze those details.
iMac Psychosis:
People who have waited for 2012 iMacs long enough that any reasonable alternative to the desktop triggers emotional pain, causing them to bash the alternative, as it would otherwise make them rethink the time and suffering they wasted waiting and trusting Apple to provide them with a new iMac.
Buys Dell XPS 27, realises it doesn't run OSX.
Until he does OSX86 and buys Magic Trackpad and now has a more powerful computer for a cheaper price.
How powerful is the 640m compared to the 680m/current imac cards?
That Dell is a decent looking AIO to be honest. Even the screen is identical in resolution. One of a kind, not quite an iMac, but appreciable.
One thing though, how in the world Dell put GT 640M in it? If one wants to compete with Apple, why not do it rightly?
Put 4 RAM slots and GTX680M in it so it can lift the finger in front of iMac. Such. Terrible. Effort.
look again at reviews of that machine, it says it is Aluminium with end to end glass and PLS display. XPS line is their premium line, they will not make it cheap.
You left out 'uglier' and 'breaks after every update', but close.
Don't understand why this is ripping off the iMac. Are you suggesting that any AIO PC with a similar form factor is an apple rip off.
Breaks every update? Not really. Google Boot-132, it doesn't break after every update.
And the Dell, Asus and some other PCs out there aren't ugly.
