Eclipse, both at home for C++ and Java and at work for PHP. Standard black on white and default font although slightly increased font size. I find it a strain to read white on black for long periods of coding although somehow I prefer it for terminals.
I find the use of plain editors like Vim baffling. On a 15" text-only screen back in the day they made sense (maybe it's a laptop thing?) but I have dual HD monitors now. I want to see more status not less. Switching from DJGPP (white on blue btw )to Visual C++ when Windows became more widespread (around 3.11) was an amazing step forward for me personally.
