The height adjustment brings with it a welcome level of flexibility and also plays into another design aspect of the screen: its wave shape. This is meant to provide a more ergonomic shape without having to adjust to a completely different type of keyboard, as with the natural keyboards that arrived a few years back. In this design the middle of the keyboard is slightly raised and the areas either side dipped. This creates a natural groove for the hands and the keyboard has a slight curve to accentuate this as well.
Of course, this slightly unusual shape does take a little getting used to: that's inevitable. But, even after an hour or so it was possible to gather up a fast and accurate typing speed with little discernable effort. It's a very comfortable keyboard, too. There's a well contoured palm rest that's properly cushioned and springy, unlike the cheap and nasty rubber strips that sometimes pass for "wrist rests". Further aiding comfort are the bottom row of keys, which are angled to sit flush with the keyboard ensuring they don't cut into the hands.
Vitally, for all its comforting features, the keyboard itself is simply very good. If you're used to old style keyboards it may seem alien at first. Each key has a very light and deceptively spongy feel to it, yet the actual mechanism remains very crisp and responsive. Consequently, every key press requires the minimum of effort, helping to reduce fatigue and increase typing speed. This, along with the ergonomic design and adjustability, results in the keyboard that remains comfortable to use over long periods, while construction is workmanlike and should be able to endure a long and hard life.
If one were top have a single criticism of the Wave, though, it would probably be its appearance. Its size has already been noted and there's no problem with its subtle shades of black, but the somewhat chunky shortcut and media control keys lend it an almost childish air - "My First Keyboard" if you will. It's something you quickly get over once you come to use it and enjoy the quality feel and comfort, but it seems odd nonetheless given the otherwise sleek exterior.
Ultimately, this is a very good keyboard. Not advanced in any great sense, but well considered and executed and available at a price that makes buying a comfortable and easy to use keyboard within anyone's budget. So, if you've been holding onto an old favourite for too long now, this may well be the tonic.
Though slightly large and chunky, the Logitech Wave keyboard is well put together and makes typing for long periods effortlessly comfortable at a price that won't break the bank.
