1. It's not a completely new OS 2. M6 was announced before the N900 was even released 3. M6 having multitouch doesn't mean it wont work on the N900, just means multi touch wont work, alternatives could be supplied (there are 3 different ways to zoom in MicroB) 4. Sound like a broken record here but, M6 was never promised for N900. As far as I can tell the MeeGo announcement has made no real difference to the N900. M6 will still be released as planned just with a different name. It'll still be debian based, it'll still use QT, it'll most likely still run on ARM hardware. So the N900 is still in exactly the same boat it was in when released 3 months ago.
