theodp writes "It was the best of operating systems, it was the worst of operating systems. When it comes to the merits of Windows 7, it looks like Slate's Farhad Manjoo and PC Magazine's John Dvorak are going to have to agree to disagree. Manjoo gives Windows 7 a big thumbs-up (a sincere one, unlike Linus!), calling it a 'crowning achievement,' while Dvorak is less than impressed, saying, 'Win 7 is really just a Vista martini. The operating system may have two olives instead of one this time out, but it's still made with the same cheap Microsoft vodka.' So, for those of you who've had a chance to check things out, are things really different this time?" Multiple readers have also pointed out that there have been problems with the download and installation of Windows 7 upgrades obtained through the student discount offer, which Microsoft has confirmed.
