I don't know too much about Mac because I had not the opportunity to meet it in Romania where I am from. About Ubuntu I must say the following in march 2007 I just started a CISCO academy curse and my PC with 384 RAM get a deadly virus on windows so.. knowing nothing about linux I was forced to tried it. I got and try the following distributions Fedora suse mandriva slakwhere and last choice ubuntu. As a newbie ubuntu was built in a way that made me learn it in 1 week how to configure it as network printer not listed as known an all main utilities. Since then I cant let it go. I works very well for my needs an it seems to be the perfect tool. More I want to tell ypu that it has a IRC client already configured to enter on unbutu help area and there are a number of permanently people that can be asked anything abt ubuntu. There i got fast, helpful and straigh answers for my problems. in the others distributions i had only to read helps and search on net abt what i need. conclusions... be my guest to make them. »
