This gives Apple until mid-June to release a final beta. That's not a lot of time. I would expect to see several Beta releases seeded to developers in the coming months. The Dock as seen in DP3 was a work in progress. We saw DHCP support added in DP3, and we should now see support for the built-in modems present on most of the new Macs.
Modems still account for the majority of Internet connections.
Carbonized Internet Explorer and Outlook Express. Microsoft showed a Carbonized version of Internet Explorer 5 at Macworld Expo in January and has committed to releasing Carbonized versions of both IE and Outlook Express to coincide with Mac OS X's release. Control Panels and utilities. Carbonizing the various utilities and Control Panels that we know so well in Mac OS 9, and getting them ready to ship as part of the standard Mac OS X installation. Expect an assortment from the Keychain to the Internet Control Panel to Software Update.
