As someone who has and loves to use a split mechanical keyboard (Ergodox-like), I'd argue against this, unless you already know the recipient wants one. Most importantly, it took me several hours over a couple weeks to get up to a reasonable speed, so if they aren't already dedicated to using a split keyboard, they may give up using it after a little bit. (Granted, my regular typing style is nothing like standard home-row typing; it may be way easier to adjust for a person already used to typing "correctly".) In addition, watch out for stuff like switch preferences. Like another commenter said, don't get a keyboard for a keyboard enthusiast, unless you know exactly what they want. To be fair, this doesn't apply to most people, as most probably wouldn't care too much, but it's something else to watch out for.

I love my split keyboard, and if you know a person will use it, it's a fantastic gift. But, just make sure it's something they actually will use, or else you're spending potentially hundreds of dollars on something that won't get use.
