Well, rolling Vista out on 5 year old hardware in a corporate situation is retarded. Whoever made that decision should be fired. The issues can really come down to a case by case basis, like particular hardware/software. Of course, the same thing can be said about Snow Leopard with some people having massive issues. And the same when XP came out

. Anytime a new OS comes out there are going to be headaches upgrading. Of course, this is why I generally don't recommend upgrading immediately. Of course not everyone can afford to buy a new machine, but then again, do they really need the new OS that urgently anyways? I do agree that Vista is a bit more resource heavy than needed, but it did get better. I at first didn't like Vista, just due to it being different. But after using it I grew to like it and found it to perform faster than XP did, in terms of system responsiveness. Of course I'm running a quad core and 4-8Gb of RAM, but if you have recent hardware it runs better than XP.
As for the tweaking, the only thing I ever tweaked was putting UAC in silent mode (which takes a few seconds and a reboot). I did the same to UAC on Windows 7 because its still over zealous even on its minimal setting. Other than that, I can't really think of anything else major I changed. The rest would be customization, which everyone does with whatever OS they use. Now I don't know if deploying and managing Vista in a corporate situation is a lot more difficult that XP was (like updates, profiles, etc). Yeah, training a whole ton of people on it sucks. Office 2007 also is a headache because of it being so different. But then again, I like to point out that anytime something new and very different comes out, it poses an issue with upgrading. This is a definite issue for large deployments, but we're talking about a single home user.
I'm mainly sick of the people who bash Vista without having used it once. And the people who bash it because they don't like the look of it (oh no, change makes me scared LOL). If someone doesn't like Vista due to it being different, then apparently they're going to be afraid of Windows 7 too. I'm fine if someone doesn't like it because they have issues with it. I agree that there can be issues with it. But if someone hasn't even used it, then please shut up. Now I won't recommend Vista with Windows 7 out, but I personally would rather use Vista over XP if those were my two choices. XP just looks and feels antiquated now.
And I'm not a Microsoft fanboy; I like Macs just as much. In case anyone was wondering.
