I haven't had any problems using Vista, its been rock solid on all the laptops that we have. The one thing that really annoys me is the auto update. Well its not the auto update so much, see we usually sleep with two of our laptop in standby in our bedroom. However once a month, these laptops will come alive in the middle of the night and apply the updates and restart. So in the dead quiet of the night you will hear the sound of Vista starting up (it wakes you up in fright, I must say). Worse still, because the laptop lid is closed, the computer will sit at the login prompt until is is due to power down (which was up to an hour). Being cold and lazy I really couldn't be bothered getting up to open and close the lid, also both laptops never seem to update on the same night, so this past week I've been woken up twice by the sound of booting laptops.
