Linux in mobile devices heats up
I have featured linux on mobile phones several times already so it won't hurt to feature another one. 
Trolltech releases the Qtopia Greenphone, "a Linux mobile development device open for unlimited software innovation. Greenphone offers a development environment that is equivalent to a GSM/GPRS mobile phone with the capability to re-flash the applications memory."
So what does it mean to have a development environment? Well, LinuxLookup provides a brief review of the Greenphone. Whilst the Community SDK is completely free, the device costs a whooping USD695. I wonder if they provide an emulator.
