In all the equipment I ever bought, only once did the warranty/ guarantee get exercised.
Equipment failures:
1) Ipod G3 failed 4 days outside 90 day warranty

2) IBook HDD failed after 6 years (and 7-10 drops)

3) Klipsch Promedia 2.1 failed 2 days after CL purchase

4) Ipod Mini failed as soon as I took it apart

5) Yamaha HTR power board failed, repaired under warranty
Of course, the list of equipment that never failed on me is considerably longer.
