Well, I'm not quite sure what to say really.
While the keynote was well presented, it didn't contain any extra special announcements or new news above what was already known really.
Biggest announcements were that System Centre 2012 is now Generally Available (GA) but that was to be expected with the RTM releases last week.
It was also announced that Windows Server 8 is now officially Windows Server 2012, but again no real surprise knowing how much Microsoft don't like using the number 13 in product names/versions.
Hopefully the keynote tomorrow might throw us some more new news.
The keynote is available here now for on demand viewing.
