Appledecided to simplify the iMac lineup by offering just one 15" model andone 17" model. The new 17" model, profiledelsewhere, has a 1 GHz G4 processor, a SuperDrive, and 64 MBof video memory.

15-inch iMac G4

The new 15" iMac runs at 800 MHz, includes a Combo drive, and sellsfor a very competitive US$1,299. Except for CPU speed, it is configuredsimilarly to the 700 MHz Combo drive G4 iMacit replaces.

There is no build-to-order option for a SuperDrive. Unlike the new17" iMac, this model does not support AirPort Extreme or have aninternal connector for Bluetooth.

Beware Apple's specs, which claims the G4 iMac has 5 USB ports. Theyget this number by adding the three ports on the iMac to the two on thekeyboard, nicely ignoring the fact that the computer itself has onlythree ports - and the keyboard ties up a port when it's connected.

Some Leopard users have reported problems with G4 iMacs that haveGeForce2 or GeForce4 graphics. When the system wakes from sleep, the screenwill be completely white, making the computer unusable. This is fixed by Leopard Graphics Update 1.0, which requiresOS X 10.5.2 or later.
