To be honest, given the recent MBP redesign, I'm fearful of any new redesign of the iMac.
Yes, it's long overdue, but will it lose features for thinness sake? Will there still be a headphone jack and SD card slot?
If it's just another Jony Ive vanity project, that gives us only 2 usb-c ports for minimalism sake, then just keep the old design.
If a redesign, why would anyone expect nothing less than...'think different'...no ports except USB-C. No SD or audio etc.
No one works anymore so no one need those ports..come on, apple knows better.
