I got a 1GHz HP PC as a hand-me-down from my son. I configured it as a dual-boot Windows XP and Red Hat 9 box. While Linux was easy to install, it seems still not ready for prime time. It won't see my external firewire drive, which works fine under XP, and worked fine when it was connected to my iMac. And bizarrely, Linux disables the on-board sound *when it shuts down*.

My problem with the iMac (other than the fact that it's 400Mhz, which makes it the slowest machine in the house) is that the boundaries between Unixlan and Macland never seem clear to me. Some things are configured using the traditional Unix config files, and some things have been taken over by GUI tools and (as far as I know) there's no way to tell which is which.

So, a lot of the time I'm happy using Firebird on XP -- tabbed browsing, no pop-ups, happiness.
