I've been considering purchasing a mac mini for some time now, and this morning I found a refurbished 1.83ghz core duo with superdrive for $479 on the mac website. I'm planning on buying two gigs of ram to replace the 512 that it comes with (pitiful, i know). I understand that this isn't going to be a top speed machine... I just want a desktop that will get me through my last 1.5 years of college, and for under $550 I think it seems like a great way to get introduced to mac. Do you think this was a good deal for a refurbished older model, or should I hold off and wait for the 2.0ghz core 2 duos to be on the refurbished page?
