Yeah, probably should have clarified that I intended no comment on the OPs comment about innovation in computer UI. Just wanted to point out that there's actually a surprising amount of evolution in design of the hammer.
Something that seems to be so simple, and has existed for thousands of years, can still be made better. I'm not a professional carpenter, but I've used a hammer a lot to do things like framing, and can confirm that many of these innovations are meaningful in function, not just form.
