Dell :: Whats Your Vista Reliablitly Score

if you right click my computer, then manage, then reliability and performance, monitoring tools, then reliability monitor (whew!) you'll see a graph that shows how "stable" vista has basically been for you. i'm just curious what everyones out there is. my last one dated 3-2-08 was 4.86 out of 10!!!! i started at 7.6. my wife has a cheapo $499 compaq with vista basic, 512 ram, not even sure of the processor, and i checked hers. in almost a year, she has never dropped below 8 points! her $499 laptop, is more stable than the $5000 plus laptop i use! the lowest i got was 4.02. i'm now slowly starting to creep back up. all sorts of different windows errors and such.
