I have been enjoying my new iMac for a few months now. I bought it re-furbbed and the specs said iLife '08, so I was happy to see an iLife '09 CD with the documentation. I assumed it was installed. I am just getting around to using iPhoto and last night I realized I am still running '08. So my question is--any downside to upgrading? I know some people aren't that happy with the new iDVD, but are there other downsides to '09? Thanks. This place is a great source of info for us Mac newbies.
