After I got my retina macbook, I disabled the 3G on my Cr-48 running Ubuntu (with Unity) and let my 10 yo daughter use it. At one point, all kids got all their screens confiscated, and it sat in my dresser for a few weeks. A week or so later, she started using my old white 2008 MacBook. It's got an Intel SSD and 4GB RAM: far superior to the Cr-48, minus the 3G radio.

While re-arranging the garage, I found some USB speakers and ran across the Cr-48, and set it up for some music in the garage. My daughter immediately wanted it back. She prefers Ubuntu with Unity to OS X and prefers the Cr-48 even though she agrees it isn't as snappy as the MacBook.
