iMovie ’08, avoid problems on upgrading, buying or replacing

I'm waiting for buying the new iLife, it is still not available in Slovenia, but it is coming in a few days. And while waiting I found a very important post about iMovie '08 you need to read before upgrading or buying the iLife '08. Click here to read it.
It looks like you will not be able to open your iMovie '06 files on the new version, also you will be incapable of using your iMovie '06 plugins. The article is so important that could cause a delay in my decision to buy the software! Why? because I will buy soon 2 macs, so they will come with it for free, while I keep the superior iMovie '06 on my notebook.
