Glad to be here
I have been running exclusively GNU/Linux for about a year now, and I am more than happy with it. I have learned more about computing and networks in these twelve months than in all my time using M$ products (since MS-DOS). The path isn't always happy and easy, that's true, but it is worth it.
I have also learned about the importance of the open source and the free software.
Now I can do all the stuff I used to with WinXP and a lot more (well, I suppose it's easy when you're not a gamer).
Now I can use computers that are just too old for the majority of people (MS users), and do productive work with them.
I am really happy when a use an old Pentium MMX 48 MB DIGITAL laptop with Slackware 10.2 in it. It's not the fastest machine in the world but I have learned a lot making it work (it used to run Win95). None of my machines are bleeding edge nor very powerful, in fact.
Now, my main problem is to find time to learn all the handbooks I have, to try to start programming in python and to be able to stay just in one distribution at a time, because, aaagghhhh! I like them all! I am also tempted to start using some of the BSDs, but wait, no. It too much for the first year :-D
I just don't have enough hours in my days.
