An anonymous reader writes "Hemisphere Games analyzes the sales numbers for their Linux port of Osmos and ask themselves, 'Is it worth porting games to Linux?' The short, simple answer is 'yes.' Breakdown and details in the post." A few other interesting details: the port took them about two man-months of work, the day they released for Linux was their single best sales day ever, and they got a surprising amount of interest from Russia and Eastern Europe. Their data only reflects sales through their website, and they make the point that "the lack of a strong Linux portal makes it a much less 'competitive' OS for commercial development." Hopefully someday the rumored Steam Linux client will help to solve that.

This article shows ways in which five buttons located on the edges of a mobile could be used in combinations to generate 325 or many more different characters, making a full-sized keyboard unnecessary. If that sounds like a tall story, remember the case of the retired 93 year old telegraph operator who used a Morse key to send a text message faster than a teenager could send it via mobile phone (see here)."
