Apple introduced three all-new, redesigned Cinema Displays today at WWDC. Each display features built-in USB and FireWire ports in a new anodized aluminum enclosure that matches the G5 and PowerBook finish.

Apple has retired its proprietary ADC connectors in all three models, switching to the industry standard DVI connector. The 20-inch and 23-inch models, which are PC-compatible, will sell for $1,299 and $1,999 respectively.

The new 30-inch Cinema Display is a monster. It requires the two DVI video ports provided by a brand new customized NVIDIA video card . It also requires a second mortgage; the 30-inch model will sell for $3,299 (plus $599 for the video card).
