I used to do C when I was really young (13~15) but concentrated on webdesign languages like Action Script, PHP, SQL to make money during the dot com boom. Made some good money.
I like Objective C, for its relative simplicity, but dislike the idea of not able to *translate* for other platform without some major (again, relative) overhaul. i.e: Some elements in Obj-C have no direct equivalent in C++
You must be making a killing with all the fuzz on apps dev.
Now I am learning HTML5, sorta a further development on what I used to do. HTML5 is light year ahead of HTML4.01.
