Should I upgrade to OS X Mavericks?

Episode 1028 (2:10:19)

Bob from Bradenton, FL

Bob has a new Mac running Mountain Lion, and wants to know whether or not he should upgrade to Mavericks. Leo says he moved every Mac he has over to Mavericks and he likes it. He downloaded it once and then moved it to a USB key to install to other computers. The only issue he sees is that older devices like old printers may not work. If he has dedicated business software, he'll want to be sure it's supported.

If he doesn't like it, can he roll back? Leo says he can reinstall the original version, but not roll it back. He would just use the built in recovery or use CMD+Option+R and it'll download and install the previous version.
