Apple started to lose me with Lion, iOS 6 and then nailed it with the quick upgrade of the iPad. Sure, they can upgrade whenever they want, I just felt slighted by it. The last few OS and iOS releases portrayed a trend which was reinforced in my mind that Apple is getting aggressive in its strategy to "force" users to upgrade expensive hardware at an ever accelrating pace by leaving out features and functionality that clearly could have been enabled on the older devices.
And then came the bugs, the half baked functions, the change of features and functions that were changed for no reason but to change them and even with that, they were executed poorly. (and please I do not need to type out examples, these forums are littered with them)
iOS and OSX no longer feels fresh or exciting, the product releases are small iterations generally speaking and new hardware is built for planned replacement cycles, no more user upgrades to extend life. To me, Apple is no longer about the user, it no longer "just works" there are so many issues, sometimes minor, sometimes major and the excuse now is "oh, you should upgrade to the newest XXXXXX product, it will work much better" line. What's worse is these OS' are not longer rock solid and stable as they once were; putting reliability in the OS in question in my mind....and I haven't even touched the disaster that is iCloud and iTunes Match.
So I tried Android 4.1 with the Nexus 7 and was blown away by its polish, its ability to make it fit MY lifestyle, MY way and not forced to do it Googles way. Is it perfect, nope, but it feels fresh, it feels modern and 4.2 from all reports is even better. Then the devices, maybe they do not use premium materials like Apple, but they give the users a ton of technology in an acceptable package for a reasonable price, often with the ability for the user to expand its abilities, such as using sd cards for expanded memory.
I feel Apple has lost its way in many regards, it has lost its way with being revolutionary, it contradicts itself in product and market and while offering still a great ecosystem hasn't shown me the future.
So for that, while I still own 13 Apple devices, and may always own Apple devices, two new Android devices will be in my house this month; change is good, I like to embrace it.
