i truly believe with the auto-disconnect app and the undervolt o/c kernel, the battery life on the n900 has improved tremendously.

in fact, from what my friends have been telling me, my n900 with autho disconnect + lehto's undervolt o/c kernel bests the battery life of both the nexus one, iphone and hd2.

all that, plus we get an external hardware keyboard. +1 for open source!
