At what point are you going to give up waiting for a new Mini… and just by an iMac?
Never, as I don't need a screen. However, as of three hours ago I gave up waiting for a Mac Mini and order parts for a Hack Mini; means I'll have to be careful with updates and compatibility, but I just don't see a Mac Mini coming before mid next year at the earliest now, and I can't wait that long.
I would get an iMac or a MacBook Pro since they have the processor option I want, but in both cases I'd be paying a significant premium for a screen I don't need. Plus the further premium for portability in the MacBook Pro's case, though I could potentially use it.
The reason I wanted a Mac Mini was so I could get an i7, slap in an SSD, and still come in under £1,000, but that's not possible with the iMac and MacBook Pro. While I can still do that with the current Mini the value just isn't good enough, meanwhile the Hack Mini I'm going for will have better specs, only be a tiny bit taller, will be quieter (silent even), will have two gigabit ethernet ports and two eSATA ports, and come in at £750 including a 500gb SSD. I don't mind paying a premium for Apple products (and to avoid the compatibility issues), especially if I would have got an Iris Pro processor into the bargain, but without that it's just not competitive IMO.
