When you read the tech press, you hear a lot about good technology, good inventions. There's a lot of exciting stuff out there for us, as consumers, to get our hands on. But at the same time, we're all a bunch of grumpy old cynics - what we really like is when an invention goes wrong.
So I started thinking about some of the most annoying inventions around. Here are some suggestions.
Hand driers in toilets: They're simply rubbish. Either they fail to dry your hands or they are so hot that they scald your skin off your hands.
Sinclair C5: We've got a lot to be thankful to Sir Clive for. But this isn't it. Perhaps it was very forward thinking, but it's not quite produced the revolution in transport that it promised. (cf Segway)
Celine Dion: Many might claim La Dion is not an invention. But you just look into her steely, robotic eyes and tell me she's not a man-made construct. I dare you.
But that can't be all. What are the worst inventions ever?
