I went to download this morning, and was bothered by a few things...
1) Macromedia is still using the V-Box technology for ESD, which means you will need to use the Classic environement to unpackage the installer. I can't believe after a year they haven't carbonized that thing, or moved on to a technology that will work directly within OS X.
2) I didn't see any option on the ESD upgrade to get a physical CD and manual shipped when available. This used to be an option for $10, and gives you some piece of mind when spending $200 on a downloaded application
3) Their servers are SLOW. It took 5 minutes just to get the main page loaded.
With all this, I may just opt for the box instead of the ESD. The bit about needing Classic to unpackage is just ridiculous.
