Define 'Real programmers™'. I couldn't care less of what 'Real programmers™' use. Use what ever you want to get the work done quicker, to generate more cash that pays everyone's bills on time. So to me, whatever these Real programmers™ use is irrelevant unless it makes the most cash.

But if your choice of experimental tools on your workstation are affecting the quality of the work negatively or if you're too busy for weeks configuring your dotfiles to work with that shiny editor, then I would just give you a MacBook Pro or just get rid of you.

Nobody got fired for buying Apple computers.
