I've had my own computer basically since I started middle school. And since then, I kind of had to go through trial and error to make things work for me on it, since no one ever really wanted to help me out when I needed it.
So, basically, when it comes to how comp savvy I am... I can make a computer work, and I can make it work well. But I'm not an expert, and I probably couldn't fix your computer for you, unless it was something simple like iTunes not working, or how to set up internet, or anything like that.
On the other hand, I can also set up my computer to do whatever I want/need it to do for me. At the same time, though, it's still a lot of trial and error, so don't ask me how I did it, because odds are, I won't be able to tell you ^^;
... Which actually kind of sucks when I get new computers and then have to try and remember it all in order to set up the new one how the old one used to be. Ah well, such is life.
Edit: Sorry for the double post...
