My Kinesis Freestyle 2 will always be the greatest ergo keyboard I've ever owned - with cables. I can tilt at 5, 10, 15 degree angles. I can move the two parts differently (and do), and with the risers, I can tilt it 90 degrees - which I'm never doing. The flexibility is perfect for me, so I keep one at home, and one in the office.

Kinesis Freestyle Gaming for me. The "traditional" Freestye has a wrist pad that's made out of a material so horrible I returned the keyboard immediately. Yuck. This was years ago, maybe newer models are better? But I'm very happy with the Freestyle Gaming in general.
