Split with major tenting is cool: https://kinesis-ergo.com/wp-content/uploads/Adv360-Pro-Asymm... I've already settled on my "endgame" desktop keyboard in the Matias Ergo Pro though. Don't like layouts that stray too far from ANSI.
The Ergo pro is an excellent keyboard. I’ve had two. Biggest problems are reliability - my first had a bunch of keys stop working in 9 months! They sent a replacement half for $99. That one stopped working 13 months later. I would google around and read some reviews on Amazon and Reddit before committing. Sadly these issues seem common. Their warranty support was… not good. Their COO didn’t really stand by their prod…
Makes me nervous to purchase one again.
