I have been given a Dell Inspiron 8000. Currently has Windows Me installed. It is to be given to a charity and the users will be non-technical but will use it for web, email and office applications. It does not have WiFi but I would like to add a simple USB WiFi adaptor that will just work. The specification is: CPU FAMILY: Pentium III PROCESSOR SPEED: 800 MHz SYSTEM RAM: 128 MB HARD DRIVE: 80 GB (total) I would like to install a Linux distro that will run reasonably and update itself safely. Distro needs to be installed on the hard disk rather than boot from CD or USB (which will get lost or damaged). What do you suggest?
