I'm not rushing
I would imagine that, like myself, quite a few IT professionals first got their hands on Vista not because they consciously bought a copy, but because a laptop or desktop PC came with the damn OS pre-loaded - and then the IT department had to 'upgrade' a PC in order to support their Vista Users.
Sadly, I upgraded my 2 year-old Acer laptop in response to the trickle of Vista-based laptops arriving in our organisation - and it's been grief ever since. First of all the RAM had to go up from 768MB to 1.5GB to get any decent performance (Processor is a 1.5GHz Celeron M), then I had to debug why remote desktop kept stopping working for a few Managers. 50% of the time my display won' t wake up again after screen-saving and then I have to push the power button to go in, then out, of suspend to carry on working.
Heaven help me if Vista downloads an update and wants a reboot because the cycle of: 'out-of-hibernate' -> reboot -> install updates -> maybe reboot again can take the best part of 20 minutes.
I am often left wondering why a simple task, such as checking or changing network configuration, takes twice as many keypresses under Vista (with default configuration) as with XP. My default printer keeps randomly changing and if I lose my wifi connection it can sometimes take a reboot to get it back..I could go on but you get the picture.
I look after around 200 PCs and it'll be a cold day in hell before I take any direct action to upgrade any of them to Vista - and before you wonder what happens when I have 'no choice' because Vista's the only pre-loaded option well - I am looking at a new core app for our business needs (veterinary clinics) that is wholly java-based and will run on a Linux desktop - even on our ageing PII's currently running good-ol' NT4.
