That was a very interesting article. I've not dug about in XCode before, it's been sitting on my system a long time 'cos I use Quartz Composer for some nice 3D stuff I do with live music...
To Daniel Harris, I think you won't have to wait too long to get what you want. Apple have been developing "resolution independence" for a while now, I think it's due in Snow Leopard, so your tiny fonts should look the same (hopefully not too tiny) on any monitor! Other things like the menu bar should take up precisely the same amount of space (e.g 1cm or whatever) rather than a proportion of the screen (1% of whatever resolution)... I think?
(correct me if I'm wrong!)
Mines the one with the ruler in the pocket, and no I'm not that excited to see you...!
