Have any Mac OS X users taken the plunge and upgraded to Lion?

Lion was released to the public on 20/07/2011.

I'd be interested to hear if anyone has done so and experienced any issues with Adobe CS4.

Adobe has released a list of known issues with Adobe products on Mac OS 10.7 Lion, which can be viewed here:

I have not upgraded yet, but I'd advise any Adobe product users to read that article before upgrading.
