To be fair, anyone moving from the iPhone/iOS teams into google will be on an anti-compete clause anyway so they'd be working on something else (friend went from iPhone to Chrome).
My dad has an iPad and an Android (samsung....urgh) phone, he's certainly not technical savvy but he gets on with both in equal measures, to him one is not easier or more difficult to use, after all unless you go delving (and unless you're techincally savvy you need a reason to go delving) you only ever press the top level icons on the screen.
It's a matter of fact that *everybody* has their day and it comes in cycles, I've seen nothing from Apples special applications group in the past 1-1.5 years to suggest anything other than they are surfing down the other side of the wave - and as much as it pains me to say it, Samsung seem to be riding straight up the other side.
If you think how quickly the fortunes of mobile phone manufacturers change, 5 years ago Blackberry was a powerhouse and now they're struggling to keep their head above water. Nokia was a behemoth.
It doesn't matter where you are now, how many devices you currently sell or what profit you currently make because if you fail to innovate and are happy to just naturally evolve then sometime soon a bigger fish is going to come into your pond and beat the crap out of you.
Edit:
Just to point out Nokia were arrogant, they continued to push symbian even though it was utter crap, bug ridden, slow, bloated utter crap. They failed to listen to anyone, everyone told them it was crap but they pushed on regardless. Then the LOL of all LOL's when they finally realised it was crap they put all their eggs in the Microsoft basket. LOLOLOLOL.
