This has, obviously, been around since Reader 7.0 came out, but with the stability of OS X, it was only today when I accidentally quit Safari and then had to relaunch it that it picked up the newly installed Internet Plugin that's installed in /Library -> Internet Plugins -> AdobePDFViewer.plugin.
[robg adds: I hadn't even downloaded Reader 7 yet; after installing it and testing the PDF plug-in, I must admit that Adobe's done a really nice job with it -- there's a page browser sidebar, searchability, comments and attachments show up, selection and rotation tools, and full zoom control. Schubert-IT's PDF Browser Plug-in still has a role to play, though, as the Adobe solution seems to only work in Safari...]
Since this subject has attracted a fair bit of attention, and quite a bit of "Schubert vs. Adobe" discussion, I took the time to do a head-to-head comparison of the two plug-ins. Please read the rest of the hint for the table (apologies for my most-basic table formatting; I didn't spend much time on it). If you see anything that's incorrect, or something I missed in either one, please let me know and I'll add it in...

[Note 1 – I couldn't find a PDF online with a table of contents with which to test this feature, so all I can state is that Schubert has a button for it, and Adobe does not. It may very well work fine in both plug-ins, but I don't have a viable test document to check them with.]
