I got an OLPC XO-1 laptop in the initial Give One Get One offer they had at launch, and sadly did not use it much since then. I powered it on last week after ages and found that it was still in great shape, and is still a beautifully designed piece of hardware. I had problems with the touchpad since when I got it, so I thought it would be a good chance to take the box apart and see if I could fix it myself. I didn’t, but I did spend a fun couple of hours disassembling and reassembling it.
I also spent some time upgrading it, but hated the new Gnome. I spent more time (unsuccessfully) searching for the Settings screen than in installation. *shrug* The other things remain great: the monochrome display at lowest brightness is still great to view in sunlit areas, the OS is Fedora-based so good old yum exists for installing software, and there enough ports for SD and USB in case the humble 1GB hard disk is filling up.
