Hi,

BTW: For Mac OS X 10.5 users, Lion completely drops support for Rossetta so no PPC apps will work anymore on Intel Macs. So if you have any old PPC apps you still use (Office 2004 anyone?, old games, etc) they will simply stop working.

And what is probably worse, Apple has dropped support for building Mac OS X 10.5 programs from its Lion Developer Tools (Xcode 4.1) so many smaller developer shops or orgs who have only one build machine will simply have to choose between adding a Mac running 10.5 or 10.6 to use as a Developer build platform for just 10.5 users or completely dropping support for Mac OS X 10.5 when they convert to Lion.

This has recently hit Sigil as it has recently dropped support for Mac OS X 10.5. I expect many of the other open source developers/programs to do the same.

So your safe bet for Mac OS X 10.5 users is to upgrade to Mac OS X 10.6 now and stay there permanently or wait and then upgrade to Lion when it is finally stable.

My 2 cents,
