Sounds like business as usual to this Tech Pro.  And lets be kind to Apple today.

When has any major upgrade gone well for anybody? 

Whenever I do any download from a major company site of any worth, the progress bar always logs embarrassingly slow throughput rates, and estimate of 2-3 hours, and I go get a cup of coffee.  Then, magically it finishes a couple of minutes later.  Thats normal in my estimation.

Phone upgrades, especially those that come without warning (Samsung and Google), are usually a bit confounding, especially when the result is a major upgrade and the user interface changes completely like Android Gingerbread to Ice Cream Sandwich.

So what?
