If Apples were as ugly as any Dell tower, I would still use them. I don't use them because the are 'cool'. I don't use them because they look 'pretty' (or 'pretty cool', LOL).
I use them because they WORK... and they keep on working, year in, year out, with no maintenance, no hassles, and no drama.
That, to me, is worth every penny of the extra cost.
