2. Worst thinking outside the box: Amazon Unbox
There's nothing really wrong with Amazon's Unbox online video service--except for the fact that you can watch movies only on the PC you downloaded them on. And it doesn't work with Macs or iPods. And although you need to download a proprietary player to watch the videos you bought, sometimes the videos don't play at all. And the Unbox software keeps trying to connect to the Net, even after you've disabled that feature in Windows. And it sometimes makes you go through a complicated uninstall process when you're fed up with it. Other than that, it's all sunshine and daisies.
