Noone should be updating a working and installed system with a new OS-

Noone should consider this process to be without trouble- at many levels-

i suggest noone makes any move to make a major change to use Lion from an existing system

If someone wants to try - they should be keeping a complete bootable backup of their existing OS hard drive-

Wait -until enough time has passed- and bugs have been fixed- checked and rechecked-


apple changes not only software - but hardware drivers and their implementation-

It can take some considerable time for 3rd party vendors to get to grips with these changes-

overall system reliability - on long and short term shows-
is more important than using the latest software OS from apple-

There are no new features in Lion that make an improvement to the operation or performance of catalyst-
