yes inkwell is not included. i would guess it wasnt ready.
someone mentioned you can install jaguar as an update. this is wrong. you can install it as an update and i did just see how it worked.
i started a thread awhile back discussing the features in 10.2 you can find it
here
if you want to discuss those issues. seemed like most people just hadnt installed it yet.
as far as speed comparisons, most stuff is faster. and cpu load is down (even on a machine from 1999, see the quoted thread for details). but some things are slower (often much slower. i dont believe this is a reflection of the speed increase we expect to see but a reflection of the BETA nature of jaguar.
based on the "late summer" statement, and the level of development of the jaguar build i would have to guess that we will not see a release at MWNY (July is most certainly NOT late summer) but will likley see it in auguest or sepetember (in late summer). This would also allow the release to coincide with the death of the apple-m$ contract (august) which could mean new browser (Netscape), and would provide apple with time to get things working (as it seems a functional os is some months away) and finish the new apps (iChat, inkwell).
on the netscape issue. apple agreeing to bundle netscape with os10.2 could have been the reason aol allowed apple access (via iChat) to the AIM network. these two are definitely getting into bed together and although i dont like aol/timewarner they might just be the only ally stronger than ms that apple could align itself with.
