Modern computers (e.g., desktop/workstation systems) are so small that
"repairing" them seems impractical most of the time. If a circuit goes,
there is no reasonable repair possible. I've had laptop screens
replaced, but beyond that and drives, it seems like a waste of time. The
newest systems are usually pretty inexpensive and faster/better (notable
exception Vista-based). 
Maybe true for you, but most home systems are easily repaired by a
12-year-old at a tiny fraction of the cost of a new system.
Only reason to get a new system is the old is obsolete for your needs.
Or to brag "I've got the latest."
