What more would you like to learn?

I want to learn about Mac because I decided to buy Mac laptop. Mac has many functions, but I’m not sure that I could use perfectly, but I want, so. Moreover, I want to know about not only Mac but also window’s computer; for example, NEC, SHARP, FMV, and so on because of my part time job. Now I do kind of campaign girl of Internet hikari one, and sometime I have to ask each customer who is looking PC, and customer asks me which PC is good or function of PC. So, if I know about them, maybe it is very useful for my job. Furthermore, I want to know about search words. It means which words are useful to search because I always cannot find what I want to find to use key words. Recently, many blogs appear, so it irritates me so much.
