Getting a new keyboard soon

My keyboard is from Dell. It's that free keyboard that comes with a computer. It's been great, but it started making squeaky noise. The noise comes from not just one key, but from pretty much of entire left side.

I remembered a friend of mine told me to get the Arc from Microsoft. Huh? Keyboard from MS? He told me it was a beautiful one, and.... yup. It looked more than just a keyboard.

I seriously thought about getting one, but I ended up talking to another friend of mine.

Me: Do you know much about keyboard? I need to buy one. Do you have any recommendation?
Him: Buy a mechanical keyboard.
Me: Huh?

Mechanical keyboard. Yes, I heard about it at one point. To me it seemed more like high-end audio systems-something expensive, yet I can't tell the difference. But he kept telling me how good it was. Next day, he brought his from home for me.

This is it.

It's made by a Japanese company called Filco, and it had blue switches (I'll explain some other time).

How was typing on this keyboard? After a few minutes I could see why people talked about mechanical keyboard. It's just different in a very good way. It's like comparing McDonald's Cheeseburger and In-N-Out. It's like "I didn't know keyboard could do this"-kind.

I looked around to figure out which one to buy, and I ordered a Das Keyboard S Professional.
Once it gets here, I'll compare it with my old Dell keyboard.
