My transition to the new Intel Mac Book Pro has been reasonably seamless - nearly all the current applications work fine under Rosetta (Apple's software emulator enabling PowerPC applications to still run) which does an awesome job.

However, I've stumbled across problems running Apple's Remote Desktop software - it isn't compatible. Users will note that it continually says 'The Remote Desktop Administrator software is out-of-date". Checking the Software Update tool doesn't provide any updates despite the suggestion to do so.

This rather useful page outlines what software is compatible, and what isn't. See also Mac Fix It information.

Some applications are a bit sluggish when launching, but in fact at a comparable speed as my old G4 PowerBook 1.25GHz. The operating system is noticeably faster - and with Intel optimised apps, this will become a little screamer. I love having the iSight camera built into the hardware, and with Apple's PhotoBooth software - this becomes a lot of fun to use.
