Ask HN: Do you use an external keyboard? Which one?

I'm planning to buy a mechanical keyboard, probably with Cherry MX brown switches. I'd have preferred tenkeyless keyboard but there aren't a lot of options available in India, so I might buy Corsair Strafe (Corsair K65 is tenkeyless but only comes with Cherry MX Red). I use a Macbook, so I'll map the alt key to cmd which should do the job.

What's your current keyboard? Which one would you choose if you had to buy one today?
