I've had the laptop with Vista on it for about 10 months. I bought it last September.
I bought my daughter a laptop with Vista on it in May for her college graduation. (She earned it!) She fumed for a few days while learning the changes and getting used to having to click 2 or 3 times to perform some tasks that require verification.
As I said, I have not tried to push Vista, nor do I run any heavy applications.
I run Open Office, Firefox, Thunderbird and Nitro PDF. I'm using Zone Alarm and Avast. I've had no issues with any of the software applications I have run.
Since I use the laptop mainly for travel, my biggest issue is setting up a new connection for each different hotel or airport.
The laptop boots up quicker than my AM2 based desktop. I suspect that most of the difference is the greater hardware overhead on the desktop.
If you are like most people and use the My Documents folder to store your files in, you won't have the complaint I have about it taking more effort to select a different folder to store files and pictures in.
The changes in how file management works are both the best and worst differences in my opinion.
I like that Vista automatically places a new folder in the chosen sort order.
I like the thumbnail preview when you go to copy or move a file or folder with the same name as existing files in the target folder.
I dislike the default folder details that are targeted for images. Along with the way they do not completely go away when you select list view.
Every time I use Control Panel functions, it takes me a moment to recall the new name and select the correct option. Such as Add/Remove Programs is now Program features, or something like that.
Like everyone else, I don't like having to tell Vista 2 or 3 times that it is okay to perform the task that I requested. Perhaps the most frustrating is having to verify that I do want to run Microsoft Update after clicking on it in the menu!
All in all, Vista is mainly getting used to doing things in different ways, or with a different name.
The main reason that I will not be upgrading my desktop systems is cost. The combination of the cost of the OS and required hardware upgrades is just too much.
Anyhow, that's the 2 cent review.
