I have one app--Adobe GoLive--that is PPC-only. I have Dreamweaver, and will reluctantly have to start using it since GoLive is now thoroughly dead and gone.
Exactly my position. I paid to upgrade to Office 2011, which is an improvement on 2008, and upgraded Suitcase - also an improvement. But GoLive is a perfectly functional application, and my main website is built/maintained with it.
I have ML on another hard drive, all up-to-date and ready to go, but no desire to use it. Snow Leopard is excellent.
