Nokia N900 - Running four operating systems

The Nokia N900 is an amazing device. We know it is capable of dual booting either Meego or Android alongside it's resident Maemo OS.
The device features a 3.5 inch touchscreen display, 5 megapixel camera with dual-LED flash, 32GB of internal storage which can be expanded with microSD, a full QWERTY keyboard and is powered by a 600 MHz processor.

But we see it's limits tested with four operating systems running on the device: Maemo, Meego, Android and Kubuntu Mobile.
