Look in the office of any Fortune 100 company - everyone uses standard dell keyboards that can be replaced easily. This includes IT, programmers, writers, management, etc.
Plus, as tyler said, mechanical keyboards are very loud and unless you work separately from your coworkers it will annoy the hell out of them.
Only gamers use mechanical keyboards.
