I use only Linux in my machines. I think that Ubuntu Linux 12.04 is usable enough to everyday but sometimes we need to use some restricted softwares and i have a virtual machine to run Windows XP, Windows 7 to get access to these programs.

Games are a trouble for virtualization but it is not a problem for me.

In the case of Nokia N900, we have the Nitdroid that is not totally completed, it`s useful, but is not completed. I think that the user experience can be better when we have a "VirtualBox for ARM" that we will run "iOS, Symbian, Android 4" in a virtual machine.

We don`t need a new operating system for N900 to do the same thing that we can do with Maemo. We need to have access only to a greater amount of softwares and integration between these operating systems.

I don`t know if it exists, the most seamless solution seems to be the QEMU but it is to run ARM systems in X86 computers or X86 in PowerPC computers.

This solution for me, is the solution for all problems about softwares in cellphone.

Why someone has not thought in this solution yet?
