The reason I use a MacBook rather than a Windows laptop might have less to do with the differences in the operating systems and more to do with the superiority of the MacBook trackpad. I have yet to encounter a trackpad on a Windows laptop that can match the feel of a MacBook's trackpad. I enjoy the generous proportions of my MacBook's trackpad and its ability to understand my intentions; it never feels skittish or sounds clacky, and it rarely misreads a gesture, click or swipe.
If you had set up your MacBook to allow you to drag windows and files around via the three-finger drag gesture, then you may have been dismayed to find that option no longer in its usual spot with OS X El Capitan. Fear not, it's still offered -- just in a different location. In previous versions of OS X, the three-finger drag option was located logically in the Trackpad area of System Preferences. For reasons that escape me, Apple moved this option with El Capitan.
To locate the three-finger drag, head to the System Preferences > Accessibility. Next, click the Trackpad Options button at the bottom of the Accessibility window. In the pop-up window, check the box for Enable dragging and choose three finger drag from the pull-down menu. Click OK to complete your transaction.
Now, you will be able to move a window on your desktop without clicking. Just hover your cursor in the title bar section at the top of a window and then drag it around with three fingers. You can also place a cursor on a file and drag it with three fingers.
If the dragging speed is too fast or too slow for your liking, head back to the Trackpad Options window where you enabled the gesture and adjust the slider for Scrolling speed.
