I love Plan9 interface, but never got used to their mouse-centric user interface. I actually like CWM - being similar to Plan9 look and feel.

oh the memories - I started with Commodore BASIC on the C-64. Second Basic (after 6502 Assembler) was AmigaBasic. Oh god, it was soooo slow. Scrolling though your code, you could watch the lines being printed. Finally I bought (!) GFA Basic - that was great! Probably spoiled my programming habits till now! :)
