Summary: If you're a dedicated Windows 8 hater, the update to Windows 8.1 isn't going to change your mind. For everyone else, this collection of tweaks, fixes, and new features is useful, but everything here should have shipped in the original version last year.
Pros: Windows 8.1 adds many useful tweaks and fixes, including a new version of the missing Start button, better searching, the ability to boot directly to the desktop, and a much-improved app store. Plus, it's free for current Windows 8 users.
Cons: The split between the touch-friendly tiles and throwback desktop mode is still awkward, and the OS is hard to use without a touch screen. While welcome, the new Start button doesn't behave like the classic version, and the Windows app store still lacks serious software, especially for gamers.
