what I want to learn about computer.

I'm not goot at computer, so I cannot use computer well.
I don't know how to use skype or other useful function.

Moreover, I do not join in Mixy now,
so I'm feeling alianated when my friends are talking about the Mixy.

So, I want to master using skype and mixy in this computer class.
If I master these function before going abroad,
I can communicate with anybody such as family and friends in Japan and America.

Although I'm not goot at computer, I'm interested in Mac computer.
This is because Mr. poza often complains about Windows,
and he recommends Mac.

So, I want know how bad Windows is and how better Mac is.
