I would never suggest getting rid of them entirely. Almost every business is a microsoft shop, at this point anyway.

But, over time company IT models change. They move from one solution to another. Moving from IIS to Apache, moving from MS SQL to MySQL, etc.. these are all backend issues. The client portion doesn't -have- to change.

I'm just saying that they could. And I don't hate MS, I hate that it'll have been an almost 10 year wait before their browser to be made modern. That part really really irks me. MS really wanted to be a part of the browser market. So they did everything and became number one in said market. Now, their browser (which has about 90% desktop share) is dragging the rest of the web down with it because of its buggy implementations of standards that almost any other modern browser can render perfectly; but nobody knows how these pages are supposed to look unless the website coder TAILORS to the bugs. Imagine breaking off bits of your car just to get it to fit into your garage.
