I don't like that. It imposes a burden on a community of developpers which is already rather small. Some applications were already never ported from the 770 to the N800 and Nokia breaks compatibility again? Whom do they think will do the job?

A long time ago, when linux changed from libc5 to libc6 I think, some kind of kludge was found so that old applications could access the old libs. Could that be possible here?
