Specifically Ubuntu 10.04. I haven't actually used my iBook with its 32 GB SSD in a while. I tried to sell it multiple times on eBay like I did my PowerBook, but to no avail. So I kept it. I decided again to try a bunch of different flavors of Linux on the machine. Some worked, some didn't. Well eventually I fell back to the one that works best (aside of Linux Mint). I didn't want to waste a couple hours getting things like sound, slower fans, etc. to work in MintPPC (not to mention the time it takes to install the actual OS is around 2 hours with my internet speed), so I installed Ubuntu 10.04 again. This time, I plugged in the ethernet cable, installed available updates, and finally got the wifi working. I also managed to get the fans working (they won't work unless you add something to etc\modules in the terminal). That wasn't too hard! So right now it's a pretty decent netbook. Internet is actually very snappy on it. The only things that aren't are things like the graphics. But for a pretty basic PPC Netbook (a little tinkering involved...) Ubuntu isn't terrible for the iBook. *Prepares for all the hate messages from OSX lovers* THIS ISN'T TO SAY I DON'T LIKE OS X! If you have Tiger or Leopard, INSTALL IT! Linux isn't the best for PowerPC Macs. It wasn't designed for it, and while it is actually pretty up to date, for performance and speed, I'd go with OS X. But just having some fun here, Ubuntu isn't all that bad!
