Hmm, nice list... Let's see how much I own...
1: Garmin GPS, and not just any! One for my bike! But I prefer my TomTom for my car...
2. USB Thumbdrive, got one from my work

3. Nintendo Wii
So, that makes three... I also have an e-ink device, but I'd rather not insult it and compare it to a Kindle, so that doesn't count...
