I've been using a Matias Ergo Pro Programmable for the past three-or-so years and it's been excellent; all the wrist pain I had been experiencing after typing ceased once I started using it, and that's held true since. The switches are tactile but quiet. The keycaps are well-sized with a pleasant texture. It's very weighty, and never moves. It has arrow-keys and Home/End/PgUp/PgDn. The cable that joins the two halves is just a standard 3.5mm TRRS audio cable. The USB cable is detachable. It does have a few flaws: the Escape key's awkwardly out-of-the-way, the same goes for the Delete key; the fabric used for the palm-rests is sort of difficult to clean; very rarely, a pressed key will get stuck and will repeat after it's been depressed.

I've also tried the Kinesis Freestyle 2... I'm much less of fond it, it might just be the worst keyboard I've used (especially relative to its price). Its switches are bad, even by the standards of membrane switches—to get keypresses to reliably register I have mash the keys so forcefully that it ends up being louder than the mechanical Ergo Pro. The keycaps are small, with a texture that's unpleasant to the touch. The cable that joins the two halves is proprietary, and the cable that comes out of the box is too short at 9", the 20" cable costs 20% of what the keyboard does and is still too short to fully utilise the split. The USB cable isn't detachable. Something about the way the right half is laid out makes it difficult to get your hand in position to use it. The Escape key's really out-of-the-way, as is the Fn key. Though, it does have a lot of macro keys.
