That has to be one of the most well balanced replies I have ever seen to a PC/Mac debate. Thanks for taking the time to go into so much detail
I do have two points that I would like to question though, the first is noise and the second is the screen. For the noise I would agree that most pre-built PC are very noisey, however I recently built a new PC and one of my main aims was to make it silent. By using large, quiet fans and not running them at full speed it is possible to acheive this goal.
The screen issue is that although at one time the Apple widescreen monitors used to be the best available, times do move on. For the same cost of the apple you can get dedicated monitors or the same or larger sizes that have been designed for colour accuracy. Not only that but depending on your main use for the computer, by selecting a suitable monitor you could have one that performs better in games too. Style and design preferences have always been personal and with so many different monitors available now there are bound to be several that are equally as stylish for much less money.
