'7 on this machine; XP on that used by MrsJim & two lappies. '7 is rock solid for 14 months now (well, I did have a couple of BSOD's when plugging in a faulty USB stick, but no damage done.) I tend - maybe foolishly - to load lots of 'stuff' on this machine which remains stable; MrsJ just uses Office and has had all sorts of probs... but that may just be her
. No, to be fair, I've had quite a number of XP crashes in me time.
All of which rambling could be abbreviated to say, I think that with W7, M$ have got it right this time... but no, I'm not converting the other machines; I'm too tight.
