Hi Jeff,
I’ve been learnt Microsoft stuff at school (VB, ASP and Access). We learned also with Oracle database.
After my training (Visual C), I got a job to work on OpenVMS with Cobol, DCL and Fortran. It was very interesting… Then I’ve been decided to install Linux(Red Hat) at home. Then I’ve been learnt many interesting tools like Perl, VIM…
I want to buy a Mac. I want it to continue to explore computer world. And also it’s easier to use an Ipod with a Mac than Linux 
If someone really likes his job, he (or she )find a way to improve himself, try new technics, push limits…
It’s the reason why Christopher Colombus discovered America…
Regards.
P.S.
My chinese is worst than my english…
