Mini-malistic Mac development environment

It looks like the “non-pro” hardware is clearly the best place for me to start; the Mac Mini and Macbook fall into this camp.
My original thought was that the Macbook would be a perfect fit since I could hook it up to an external monitor at home and take it along with me when I need to go mobile. Then it dawned on me, I don’t really go mobile. I sure like to imagine all of the cool places I would go with it, but in reality such occurrences are few and far between. For when I really do need a mobile, I’ve go the XO and the ThinkPad, and who knows, if this Mac stuff pans out I wouldn’t mind picking up a Macbook or a MacBook pro. That said: Mini pricing seems very reasonable.
It looks like a Mini with a 2GHz CPU, maxed out with 4GB of ram, the default 120 GB hard drive, and an Nvidia video card that can drive a 1900×1200 display can be had for only $750USD. This seems more than adequate for setting up a Mac development environment; heck even Java would do fine here. What a steal!
The hard drive size upgrade prices are insane. If I need more space, I have a beautiful external LaCie hard drive that has been looking for a home!

Evaluating the ADC Select Membership

Apple offers 3 levels of memberships: online, select, and premier (0USD, 500USD, and 3500USD respectively). They differ of course on features. For the time being, the select looks the most reasonably priced so I wanted to learn more about how it might make sense.
From what I read, the biggest perks are the 2 support tickets and the hardware discount (10% on normal hardware and 20% on pro hardware). Access to outdated WWDC material is not very compelling. While the online “coding headstarts” might make sense, neither seem justified by the price.
The hardware discount is interesting, as the discount essentially cuts 500USD off of any pro hardware, and then you end up purchasing the select membership with what you have “saved”; so this alone can make the membership worth it. One might wonder why you wouldn’t simply purchase this membership when you want a discount and let it lapse when you don’t; but apparently if you do so, you will no longer be offered the discount. In other words, once you purchase it you have to keep it up.
For me it looks like the best approach would simply be to start with a Macbook and take some time to ramp up and get familiar with things. If it makes sense to take advantage of the support tickets and faster hardware (every year or so) then the Macbook could get passed down to someone else and I could find out how helpful the tickets really are to me.
