Hello. I am using iLife'08 or '09 (not sure which one came with my MBP 2010). I am considering to upgrade to iLife'11 especially for possible additional features to make Ken Burns Effect videos. In general, is it worth to upgrade? I read some postings that when iLife'11 came out last year, there were many problems such as users losing photos in iPhoto'11, etc. Have these major issues been fixed? Is the software suite reliable now? Thanks.
