Correction: You insult me with a patronizing 'quiz' to push your own agenda. All I have done is explained a lock in to the apple ecosystem, in mobile apps. When you buy an iphone you are limited to whatever the new iphone is when you come to upgrade. When you buy a phone on another platform that I have mentioned then you have a much wider choice of an upgrade handset in that platform without losing your apps. What is contrived about that example? Correct. Nothing.
Parody of your ridiculous position sucks don't it. You try to define a new to the universe version of lock-in. Problem is everyone else knows and accepts what you are trying to play as new and nefarious. At least you used the term platform this time. I think you fell flat on the upgrade within the platform again though, every viable platform provides an upgrade path. whether you like that path or not weighs on whether you buy into the platform in the first place.
Personally I find nothing in the Android world a significant upgrade compared to an iPhone 4. Spec-whoring can come up with little differences on a phone by phone basis, but overall where's the well executed feature that's an upgrade draw worthy of creating a platform to platform shift. It's not there. And if it's not there, there's no real upgrade. In platform or cross platform.
So trying to create a platform shift scenario with a LARGE paid app investment where no platform shifting motivation exists IS contrived. Especially when you ignore the whole set of reasons people buy into platforms in the first place, which is the platform itself. You keep leaving out all the important stuff to try and make your point and that just constitutes a heap of fail. Kinda like this:
