Yes

A couple of the headline features are airplay streaming to Apple TV (but only for machines bought after 2011) and Facebook/Twitter integration (which if you read the small print will not happen until later in the year).

Having a read of the forums on the Apple website it seems some users are having issues with older versions of some software, things like Parallels and some of the Adobe CS Suite. I would check all software/hardware compatibility before upgrading.

True.

I have to upgrade to Parallels 7 so that I can use windoze. What do I use windoze for? The Blackview firmware updater. That is all. I must have an old windoze machine somewhere in the loft which can do that. Everything else I have works fine.

You could try Oracle's virtualBox - it runs under OSX ML without issue (for me anyway) and is free, although whether it would allow you to update a device over USB is a bit hit and miss.
