Something, something, something, Mountain Lion:
If you haven't heard yet, Apple released its latest version of OS X codenamed Mountain Lion today. It's available exclusively in the Mac App Store and costs a mere $19.99. If you know how to use Google, you can find all sorts of other people writing and posting on blogs about all the new features and new services included in its release.
Now go get it.
I ponied up my $20 and it took only 35 minutes to download and each of my Macs upgraded in roughly 30 minutes with no negative impacts operationally yet to report.
My only complaint was for upgrading my iMac's OS X Server software. The App was not searchable in the App Store at the time of my OS upgrade so I had to Google it and found the direct link to iTunes online at Apple.com: http://tinyurl.com/cc9thzw
Oh, and as usual, the damn thing runs hot. I have a Early 2012 MBP 17" collector's item running 10.8 and man, it is hot!
I'm going to try to reset my SMC tonight to see if that helps any. Who knows. Then, I'll try killing all the Apps running in the background on my iOS devices (Geek humor).
Enjoy!
Update:
The SMC reset seems to have helped a great deal, coupled with the fact the Spotlight indexing is done. There are some preferences I am discovering were reset by the upgrade (exclusions in Time Machine for example) so if you have your VMs excluded for DropBox folders for instance, go check them. Great update so far in my opinion.
