The OSDL is supposed to be launching an initiative to bring Linux to mobile phones on Monday. Fantastic news! The article does a good job of outlining some of the technical challenges. Power management under Linux has been something that could be improved on for a long time, and combining the need for power management with the need to show realtime OS response times could present some tough challenges. The Linux kernel group is also an idealistic bunch. They tend to hold out for something that satisfies all the requirements instead of tossing any old feature into the mainline kernel. Sometimes that forces the evolution of some really unique solutions. I think there’s room for a ton of improvement in terms of mobile OSes, and having the Linux kernel evolve in that direction would spark the kind of innovation I think we need.
