Other than that, I haven’t yet noticed too many other dramatic changes except that iCloud is better integrated. So far, the handiest tip I’ve seen in using the slightly altered UI is to place two fingers next to each other near the right edge of the touchpad: this calls up a “fat scrollbar” at the right-hand side of a scrolling window and makes scrolling very easy. I fired off the download package, and it took me through the rest of the process in about an hour (half an hour or so to unpack the files and prep the machine for the actual OS install, and another half-hour to perform the installation).

I’m not sure if it was heavy demand for the approximately 4 GB download file, or online Internet traffic related to the Olympics (the US women’s soccer team played a very strong French team, and managed to beat them 4-2), but it took nearly two hours for me to download the file. When I got the news yesterday that the latest 10.8 version of OS X, aka “Mountain Lion,” was available, I jumped on the opportunity to download and install the new OS upgrade for a mere $19.99 at the Apple Store.
