While it's a perfectly fine and affordable Bluetooth keyboard, the Logitech Wave has minimal ergonomics. The keys rise up slightly in the middle and there's a comfortable wrist rest attached, but the layout is the same as any other keyboard, with no splitting of the keys to open up your arms or keep your wrists straight.
