Brilliant Brainstorms is a weekly summary of some of the best/most interesting brainstorms from the Ubuntu Brainstorm site.
Since Ubuntu can be purchased pre-installed from a number of vendors (including Dell), it would make sense to add this option to the Get Ubuntu page.
With the increasing number of small-screen netbooks, it is important for Ubuntu to gracefully scale down to lower resolutions, without losing functionality.
Linux is able to run quite well on computers that many people would consider junk, but, unfortunately, most people still just throw away old computers. Due to the low risk of installing a new OS on something you consider junk, this would be a good place to start a marketing campaign.
Relatively few people think about the insecurities of unencrypted wireless networks, so warning users about it is a good idea. It is important, though, they this message not be a scare message. It should just inform the user that they should not transmit sensitive information.
When a user gets stuck with a file that cannot be opened with the installed software, it would be much better to prompt them to install some piece of software then to let them go find some .exe and then complain when it does not work. Also, for any user who gets a file from someone, this would save time.
