RoaringApps - App compatibility and feature support for OS X & iOS

Lion works fine on any Core 2 Duo or later Mac. It is not specific to 32 or 64 bit. The early Mac Mini's were 32-bit only, but had Core 2 Duo CPUs. All of the beta releases worked fine in 32 bit mode, and so does the final release.

Also, you can still boot into 32 bit mode by holding the "3" & "2" on boot up, on most Mac's running Lion.

Entourage works fine. I use Office 2011 for Word, Excel & PowerPoint so I can't speak to how well the 2008 versions work.

The previous posters statement about the installer requiring Rosetta is not true. I did a clean Lion install and did a clean Office 2008 install. The installer worked fine for both versions 2008 & 2011.
