GMail one day decided to no longer show my emails from my customers in my Inbox -- I have to search for them one-by-one. So every few hours I have to search for keywords. I also get gmail from another account, and he gets mine. At least it is not as bad as Skype. Woke up one day a week ago, hit Upgrade, and now Skype doesn't work -- whatsoever. Nothing I can do. Essentially if I didn't have experience as a level 3 support engineer, I'd be out of business.
