Various reports have been coming in confirming the announcements of new PowerMacs tommorrow by Apple. As well as one unconfirmed report (so take with a grain of salt) of price drops on the new machines. Apple/Ingram has discontinued the current line of PowerMacs.
Jaguar also appears to be ready for public use -- Xlr8yourmac.com posted a reader report that a new iBook came with a copy of Jaguar.
