Tabs give me the possibility to indent code as I prefer it (Tab=4 Spaces) without forcing anyone to view it exactly the same way.
IMO your argument is faulty. If you code with tabs set to non standard width then odds are your code will look totally wrong on someone elses screen. And vice versa. Code written where the indent is 4 spaces but the editor autoconverts 8 spaces to a tab is going to look wonderfully screwed.
IMO the only sane way to indent code is with spaces. There is no ambiguity about how the code should look when its displayed then.
First they ignore you, then they laugh at you, then they fight you, then you win.
