Whether or not people love or hate whatever new design it gets, I have always had a strong feeling that it will be radical.
(Not directed at
@Icaras personally, but as a general observation...)
"Radical" should never be a design goal in its own right - the "giant laptop" design featured in this thread is a perfect illustration of that sort of form-over-function nonsense. Guess what - one reason some of us choose desktops is that we like to choose our own keyboards and pointing devices, and decide how far back we want the display placed... I actually doubt that this is a serious contender - just a result of Apple engineers patenting what they had for breakfast - and it shouldn't be unless they fancy launching an xMac or MacSuperMini alongside it to fill the hole.
(And, yes, I really want a glass surround so I can enjoy all the dust bunnies and cables that live behind my screen)
Personal computing is a mature technology - what a lot of us want/need is just a practical desktop system that keeps up to date with the incremental improvements in CPUs and GPUs. Yes, Mr Ford, we're asking for faster horses because we actually know the kind of work we do and what tools we need to do it.
That doesn't mean Apple can't launch a radical new product if they think they've really cracked the next new paradigm in computing - or the original Lisa/Mac would never have happened - but don't do it at the expense of your only credible mainstream desktop offering. Remember - the Mac was launched in 1984, the Apple II (in the form of the IIgs) wasn't discontinued until 1992...
If Apple want the next iMac, they should go take a long look at the MS Surface Studio...
