I was going to pull the trigger soon on a mini for my business and then of course see the recent bump on the white macbook specs.
I am going to still go with the mini as I need to replace my ailing Dell (only 1.5 yrs old), but I also have a dual monitor setup that I would like to use and a sweet Logitech mouse. I would need the apple keyboard (could survive without it), and the cables for my monitors. I'll bump the RAM and HD. I already have an external FW macally enclosure with a 1TB drive, so I could even hold off on the HD upgrade, but will probably go for it so I don't have to worry about any data and apps that I've already loaded.
So, Still coming in quite a bit under a macbook setup.
I have a MSI wind that is extremely portable, so it is hard to justify getting the macbook right now, but it would be nice to have a little extra screen real estate (just a small bump is enough) as I do get a little loopy when I am looking at this thing for an extended amount of time, but dang this thing is mobile and really peppy with Win 7.
I will probably end up getting them both (macbook a little later) and buy refurb to save additional cash. At this price point you could have two really decent machines with apple care (third party purchase) for well under two grand. Makes "business cents" to me.
