Not really. Not compared to OS X, namely for mobile use.
- The Control Panel is a jumbled mess compared to System Preferences.
- The Start Menu requires deeper navigation then the Applications Folder.
- I often don't even need the Applications Folder since my frequently used things are in the dock.
- More programs need installation due to a unified registry then .App programs do. A .App file is like an executable folder and often uses config files inside the .app rather then depend on a system registry. When an app does need to be installed, you usually just dump it in the Applications Folder.
- Integration with my phone is easier (I'm an iPhone user. I care more about the OS then the hardware, and I like iOS over Android).
- You rarely, if ever, need to bother with drivers. Heck, the Xbox 360 Kinect is FAR easier to setup in OS X then in Windows.
- You rarely, if ever, need to clean a registry (because there isn't one) or clean up startup programs.
- The multitouch gesture integration makes laptop use far more efficient.
- I'v had less issues connecting to and selecting wifi networks in OS X then in Windows.
These little things add up in the use experience. Sure, some of these may have third party equivalents, like the dock, but I specifically don't want to mess with stuff like that on a laptop. I want it ready to go out of the box or after a reinstall of the OS. Less tweaking means I can toss my apps and files on an external drive, reformat, and quickly be back where I was without installing anything. Others, like Windows more complex folder hierarchy or unified registry, are inherent of the OS. When messing with this stuff on a track pad, it can get frustrating quick. Doubly so if the trackpad is small and offset like so many are, and like I'v said before, a laptop should not be dependent on external devices.
