The folks at CNET have given Windows Vista Ultimate a thorough testing. Their verdict? Buy it if it's already installed on a new PC, but skip it if you're merely upgrading. Though they found MS' new OS very stable, they felt there weren't enough new features in it to merit an upgrade. Also, chances are if you do upgrade, you'll need a stronger PC to take advantage of the new features. In other words, that old, dusty Dell ain't gonna cut it.
Among the things they did like...
were the OS' new Instant Off button which caches all your open files and lets you shut down immediately. There were also better support options throughout the OS, with a much-improved Help section that helps with troubleshooting. But in the end, Vista left CNET with that sinking "is that all" feeling.
"Compared with Mac OS X 10.4, Windows Vista feels clunky and not very intuitive, almost as though it's still based on DOS."Ouch. And with Leopard coming up, it looks like the gap between the two operating systems will only get wider. – Louis Ramirez
