Mac OS X Lion

Mac OS X Lion install is done as of today. If you upgrade your system and want to keep the installation file from the AppStore Download make a copy of it before starting the install process. After Lion is installed the huge file downloaded from will be deleted.
Warning: there is no Rosetta emulation layer any more – so all PowerPC programs on your system will not be running any more.
… and do plan some time for getting used to the new feature called „natural scrolling“ 🙂
