Maybe Apple will buy it and / or integrate it fully into the Leopard-OS
What would be nice is the ability to virtualize another copy of OS X within itself. It would be fantastic for developers wanting to testing their applications in older versions of OS X. Of course, that may not be terribly useful if you have an Intel Mac and want to test in Panther which is PPC only.
I can also see plenty of value in doing this for OS X Server, running multiple virtual servers on the same 8-core box.
I've gone ahead and pre-ordered my upgrade to Parallels 3.0. Hopefully it's as good as they say it is, though I have my reservations with all the new features - particularly, how will performance be affected? In my experience, the most recent released versions tend to perform much more slowly than the first versions that were out last summer. I've even thought about downgrading because it gets so bad sometimes - apparently they're doing something with writing memory to disk, which may improve stability but it sure slows things down to a crawl sometimes. Kind of annoying!
The next weeks will be interesting for sure, both for Parallels stuff and for OS X software in general. It's about time -- so sick of all this iPhone crap!
