Ubuntu is a good choice for getting started with Linux. There are better distributions for desktops, servers or people who want to tinker. But since Ubuntu is based on Debian, its a good starting point to lean that if at some point you want to go 'full geek' and pull up a command line. If not, it may serve you as your final O/S for the foreseeable future.
Ubuntu is Bantu for 'I don't know how to configure Debian'.
