I'm happy to learn the new mini supports dual monitors out of the box. That is worth the price of admission alone. I'm thrilled I sold my Mini Core Solo. The 2009 will cost me $200 + the proceeds. Well spent I think.
It's HI-LAR-IOUS reading some of these posts. First Apple was bashed for letting the mini languish. Then it was mourned because of rumors Apple might kibosh the mini altogether. Now we know the mini lives and with a slightly improved chip speed, but at least the lowend is now capable of 1080p w/o hicups, and the aforementioned new graphics and video connectors, all for $19 more (cost of the Apple Remote that is no longer included) than the previous version.
My first mini was a G4 1.25. I think it cost $499 (that is 2005 dollars). So $599 for a MUCH improved mini is not that outlandish. Bargain hunters can go to the usual online stores that sell Macs TODAY and buy a 2009 lowend mini for under $599. One store has it for $578 shipped free + $11.50 cash back @ FatWallet. Another $594 - $17.82 cash back (Live Search) - $25 rebate, for a net cost of $551 and change.
Now if that is still more than you can afford, Dell has an Inspiron with your name on it with Vista Basic. It's not elegant or trouble-free, but it is cheap. Go ahead. I don't think Apple is ever going to make a machine at a price point that is going to make you happy.
