Surely it will be a completlely new OS by flashing rather than just a new firmware, which I understood to be like a progression from say PR1.2 to PR1.3? I can't honeslty see N900 users ever being able to upgarade from maemo to meego via a firmware update?

I may be expecting too much but hopefully a user can dual boot maemo or meego from the emmc in the near future or at least run it from the SD card at a reasonalbe speed/perfrormance which doesn't seem to be the case at present with meego 1.2 due in just under a month.
