in a year, maybe it'll get a new revision by then? Even though I really like it, as it is, it's still sort of a half-hearted attempt. You'll need a display, unless you already have one. When you add that cost, even something cheap, you're at 750-800 or so. You really have to weigh that against an entry level refurb iMac that could/would be available in a year. It will also have thunderbolt, slightly/much better video, a quad core CPU, 4 RAM slots, no clutter. You can get this machine right now for $999 - and it's probably both a tad more robust for heavy uses, and a bit less fussy to set up and use - though there's not much in it.
The stupidity here is that if you need the extra performance for creative work, you probably don't want the iMac's glossy display, but if you buy the Mini, you don't really get the extra performance. See this tiny little comparison

Though the mini is probably good enough for a lot of work creative or otherwise...
