Aside from the unacceptable compatibility issues, Vista was not very well thought out. The much ballyhooed search function is worthless since it doesn't show keywords in their context. The new file management system is infuriating since it eliminated easy access to commonly used features like move/copy and up one level. It's easy to put files in the wrong folder since the target directory tree moves with mouseovers. I get frequent crashes. Programs won't close even in task manager. It's coming off like a beta release and is beginning to remind me a lot of that dog of an OS: ME. Hell... even the MSN browser/mail client doesn't work well with Vista.
