The "We're Linux" contest was set up by the Linux Foundation to encourage Linux users to demonstrate in 1 minute videos why they used Linux, and why others should try it as well - Linux commercials, basically. There were 90 contest entries, and a combination of community voting and a panel of judges led to one winner, and two runner-ups. The winner can be seen below, but I personally find the first runner up to be better.
While I think both of these are pretty well done, they do fail in one important aspect. We are all geeks here, we'll get the videos. But what about the majority of the world, who have little knowledge on this whole Linux and Free thing? I think that if you want to use the Free/open aspect effectively in a commercial for Linux, you need to clearly show two things. One, what Linux actually is. Two, how being Free/open benefits you, the customer. While these videos are well made, they do not address either of these two points.
Microsoft also pushed out another Laptop Hunters advertisement, this time about an 11 year old kid buying a gaming laptop.
The kiddo wants a laptop with "speed, a big hard drive, and a gaming computer", for under 1500 USD. It follows the known format, and they end up buying a Sony Vaio with Blu Ray (which is apparently something to get very excited about) and 5.5 hours of battery life.
What's there to say, other than that I loved the facial expression of the mother when talking about the Macs? The ad follows the basic format, and it's fairly effective at highlighting the fact that on the PC side, there's lots of choice.
