> Mechanical keyboards are ideal for programmers and fast typists

Don't fall for this hype. I've used mechanical keyboards for over 20 years and switched to non-mechanical 6 years ago. My typing has been never fast. You don't have to push/raise your fingers all the way down/up when you hit the key or when you release the the key respectively. That adds to the latency as well. The flatter the keyboard the faster it is - of course coupled with the actual mechanics of the keyboard. But mechanical keyboard? Not anymore for me!
