Do take your head out of your arse Essruu for just a moment. Until recently there wasn't an apple store in Southampton. And since I live in Huddersfield, that is of no use what so ever, is it. The nearest apple store and or repair centre is in Manchester. We are students. So that is a trip on the train, twice, to take it there and pick it up. Or we can post it off in the box they (dont) send.
On the flip side, if my PC breaks (that I built), it is fixed on the spot, and when I take it apart I don't have some apple fascist breathing down my neck because I've voided the ****ing warranty.
Apple make it nigh on IMPOSSIBLE for the average user to fault find for them selves, throwing up all kinds of obstacles (locked down hardware, restrictive OS etc).
