17'' iMac G5 Out of Stock
Apple had previously discounted the 20" iMac G5 to move the final inventory. Initially, Apple had been selling both the Intel iMacs and older G5 iMacs side-by-side. Now the transition appears to be completing.
With stock of PowerBook G4's also dwindling, Apple had stated that PowerBook G4's would be sold while supplies last. The 15" MacBook Pro is expected to ship later in February, but unless Apple releases other form factors soon, there could be a hole in their laptop lineup in the 12" and 17" configurations.
