Then this was never marketed towards you in the first place. Apple isn't looking to dominate the market with cheap alternatives. None of this should be news to you.
For aesthetic reasons. How often do you use it anyway? Why not put all the ports on the front in that case?
I'm not sure what this second part is that is coming up when I quote you, but I can only assume it relates to the SD slot. In answer to your question, I use the SD slot very often, as do many people who have things like digital cameras, video cameras, etc.
As far as the first part is concerned - The original Mini was marketed towards me, and others like me. Tell me, why is it that Apple could sell a computer with a PPC processor and a discrete GPU for $499, but once it was made with a generic processor and integrated GPU it suddenly jumped to $599? (In case you didn't know, it's a rhetorical question.) Now it is $699? In the middle of a recession? Seriously?
As a college student, there are two major types of laptop owners - the rich kids who have Macbooks, and the ~70% of us who would love to own a Mac, but just can't afford it. It is a real shame, because we humans are creatures of habit, and once people become comfortable with an OS, they tend to stick with it. It is a real missed opportunity for Apple, all because they would rather focus on the 10% who have the money to blow on a fancy case.
Edit: When I first hit "Quote" the forum wasn't showing your second quote, hence the weirdness at the beginning of my post.
