Installing the latest Adobe Reader causes Preview to be overwritten by Reader as the default PDF reader in Safari. There's a setting in Adobe Reader prefs that should aloow one to change the setting, but it is greyed out. Thanks Adobe! You'll need to go to your HD/Library/Internet Plug-in folder and remove the Adobe plug-ins. Quit and restart Safari, then Preview is default again.
iMac, Mac OS X (10.7.3)
Here is the instruction page from Adobe

Thank you for this - exactly what I was looking for.

Really glad this helped you.
(Better late than never, eh?)
I found them in the /Library/Internet Plug-Ins folder, and removed them. PDFs within Safari open with the native Preview. This is handy.
Thank You.
Thank you Bruce!
THANK YOU THANK YOU THANK YOU.
One would think Adobe was created by Microsoft!!!
