AppleInsider updates after a long break, and under new management and claims to have detailed specs on new iMacs.
According to their report, the low end with feature a 15" LCD at 867MHz at $999, with the rest of the line sporting 17" LCD's ranging from $1199 - $1699 and toping out at 1GHz.
15" LCD, 867MHz, CD-RW, $999
17" LCD, 867MHz, Combo Drive, $1199
17" LCD, 867MHz, SuperDrive, $1499
17" LCD, 1GHz, SuperDrive, $1699
While AppleInsider has had a good rumor record in the distant past, the site has not seen regular updates and has also seen a change in management. As a result, overall reliability of its current incarnation is unknown. (Note, the exact same specs were posted on MacNews.net.tc but it's unclear which were posted first)
Our own information suggests that Appleinsiders' prices/specs are incorrect, and we expect the new models to have $1299, $1499 (15" LCD, Superdrive), and $1799 (17") price points with no CD-RW model.
