Adobe has released the new Reader version corresponding to Acrobat 8 released a few weeks earlier and I’m very pleased of the mac version especially, because it runs natively on Intel Macs and has been partially rewritten in Cocoa (the main binary is still linked to the Carbon framework, but some parts like the welcome screen are definitely Cocoa).
Some of the new features besides the ones described on the product page include image selection and copying! Click on an image of an unprotected PDF file, click on the right mouse button or hit Command-C and the image gets copied to the system clipboard. Very cool.
