I had a Nexus 7 go AWOL at Christmas and I've never had such a shambolic customer service experience.
They have absolutely no respect or customer service ethos when it comes to people who are actually paying them real cash money.
Not in a million years would I sign off on hosting a production project on App Engine.
I had a support guy tell me I had to get Apple's legal team to contact Google so I could use the "Mac" trademark, because I happened to be selling a piece of software that ran on OS X. Like that's ever going to happen. My ad simply said "Try ____, a better way to _____ on Windows and Mac.", linking them to http://www.apple.com/legal/trademark/guidelinesfor3rdparties... didn't quite cut it, apparently, even though it clearly states that such use is acceptable under "2. Compatibility" near the top of the page. i.e. I can say my product runs on Mac if in fact it runs on Mac.
Approving a ten word ad takes Google over a week, in my experience. Baffling.
All this with their adwords $100 free trial. All that trial did was convince me that I should never ever in the life of the universe commit any money to Google, because they made it starkly apparent that I would never get what I paid for... running honest ads for honest products in a reasonable timeframe. I went with other ad networks in the end and had zero trouble whatsoever, and infinitely faster approval times. I suppose I may have had a smaller audience, but the headaches Google causes aren't worth the extra money.
Someone is going to come along and pull the rug out from under Google eventually. You can't rest on your laurels forever.
