To be sure, I think OS X 10.8 Mountain Lion is the best OS Apple has ever released. It feels like a completed version of what Mac OS X 10.7 Lion should have been. It's fast, it's clean, it melds some iOS concepts to OS X and, for the most part, it just works.
That being said, no OS is entirely perfect and there are some gripes my colleagues an I have about Mountain Lion. We've compiled them into the list below. Now, most of these gripes are minor and they'll probably be corrected in future updates like 10.8.1 -- at least, we hope so.
After reading through the list (which may grow) feel free to add your own gripes in the comments. And please, don't let this list of minor gripes put you off the OS. It really is the best one Apple has ever released.
CalendarAccepts invitations in the top calendar, not the default Exchange calendar (and not the account that received them).
Displays menubarMirroring only.
Notification Center@mention tweets don't show from people you don't follow.
Notification Center/MailClicking on an email message in Notification Center should take you to that specific email's inbox in Mail, NOT the universal inbox for all your different email accounts.
Stock WidgetYou can no longer rearrange the order of stocks. Stocks don't sync with Stocks app on iOS devices (they never did, but they should).
General:Numerous graphical "tearing" issues throughout the OS on the MacBook Pro with Retina Display. Most prevalent in TextEdit and Mail. "Open Recent" has disappeared from opening dialog splash box in many apps, most notably iWork apps. No "share" button in TextEdit. "Save As..." behaviour is completely contrary to how it worked pre-Lion. MacBook Pro with Retina Display has serious wake-from-sleep issues. Requires hard reboot more than 50% of the time.
3rd party apps:Microsoft Office apps refuse to hide. Sandboxing (or something else) seems to be preventing the iStat Menus Dashboard widget from delivering data on CPU processes.
