Another use-case for not killing background processes is on-device development. Lets say I'm on the train, doing some coding, and then compile my project. The last thing I want is for the process to be killed off because I have left it compiling in the background while I'm doing something else.

One of the reasons I was initially drawn to the N900 was because it is a fully functional computer that can fit in my pocket. IMHO a mobile computer should be able to do everything any other computer can do. Yes there are hardware limitations on a mobile device - I know that compiling on the device will be slow and will reduce my battery life but I don't have a problem with that.

I accept the hardware limitations but I don't want artificial software limitations imposed on me by sub-standard multi-tasking.

Given that Jolla's core is Mer, I expect it will have proper multi-tasking anyway.
