Apple Switching to Intel
Steve Jobs announced at the WWDC keynote today that Apple is switching to Intel processors. MacNN has live coverage. The bottom line is that Mac OS X for the last five years has been running on Intel, the switch is expected to be complete in two years, and Rosetta will allow PPC apps to run on Intel-based Macs, transparently. If you're using Xcode, it is small changes and a recompile; otherwise, you might be seeing a lot of work ahead of you. You will be able to order the 10.4.1 preview for Intel today.
You have plenty of time. The rumors were only half-true.
Apple is adopting Intel, but is not "ditching" IBM.
New G5 towers will still be around for at least another year, and probably at least two. Intel is probably going to start by replacing the G4 CPUs in Powerbooks and minis.
At the Stevenote, he informed devs that they would be supporting both platforms for a long time to come.
Information wants to be anthropomorphized.
1. If Rosetta works as well as demonstrated (Jobs showed unmodified PPC versions of Photoshop+filters and MS Office running happily and fast on the Intel Mac box) then this will be less painful than you think.
2. The way the Intel and PowerPC raodmaps are going I think in three uears time there will be a HUGE difference in capability. Jobs was demoing a Pentium 3.6GHz quad for God's sake!
As others have pointed out elsewhere in this thread, the dev kit includes the hardware. They aren't just shipping a Tiger CD you pop into your dell.
