I would also sing "If I had a hammer...".
Luckily, my brother is a programmer and he knows almost everything about computers. Well, I know too, but... when there are two heads, it's better.
Also, I am almost a maniac concerning advance information. I always check and check and check. That bothers even me sometimes, but, it works well in most cases. Sometimes, if in the beginning I want to buy something, after I check the info I buy something else.
