I believe there is significant value for having the ability to provide at least some of the chronologically listed detailed call logs on the device itself: for example, when away from your computer, if you are called several times in succession by someone in an emergency, and then are called again by someone else, it is currently impossible (on Symbian S50v3 - Nokia E71) to know both how many times and when (except for the last time) that that individual called.

Every other phone I've had (except for the two Symbian S60v3 phones - N95 + E71) have had this ability. In addition to, of course, the other two I listed on my first post.

BTW: for those of you who are interested in these features, I encourage you to sign up for the Maemo Bugzilla and vote for the Bug ID listed above (5552) - that link is for the Bug tracking the ability to show which kind of line (listed in the address book / contacts) a call is related to.
