Amazon is offering the Logitech Cordless Desktop Wave Set for just $49.99 shipped, originally priced at $89.99. Its “keys undulate across the board in a wave-shaped contour that mimics the changing lengths in your own digits — keys are at their highest on the outside.” Product page. Video after the break.

Like other ergonomic keyboards, the Wave includes an elevated palm rest, though not as extreme as the platforms of old. It’s also covered in a lightly padded vinyl upholstery that feels soft yet firm under the wrist, as well as a Goldilocks amount of tackiness (i.e., not too slippery, not sticky, just right).
