Since I have a daughter, there are things I do with her or for her on the computer or my iPhone.
Her computer is my old Pentium 3 machine with 786MB RAM and a 20GB hard disk. I have installed Edubuntu 8.04 on her machine. That’s the latest version of Ubuntu that works on that old hardware.
Her favorite software on the computer is gcompris.
She also spends a lot of time using my iPhone.
