Superdrive'd TiBooks or Not?
ThinkSecret and MacOSRumors are jumping on the November 5th bandwagon started by MacPlus.
Both sites dismiss the possibility of Superdrive'd Powerbooks for this release. This is also reinforced by the News.com article quoting Joswiak.
A MacRumors source, however, verifies the existance of prototype Powerbooks with Superdrive at this time, suggesting that the release is imminent. The availability of large quantities of these drives, however, is unknown.
