As a 3GS owner can I please go back to iOS4 while we're at it? After refusing to "up"grade to 5, I upgraded to 6 by accident. It's no longer my primary phone but still works great as a 2ndary camera, alarm, weather checker, etc, and it was much better on iOS 4 than 6.
Apple's decision makes sense for them though. By making upgrades insidiously easy and backgrades impossible, nerfing older products will virtually force users to buy new iDevices. It's kind of like micropayments. "Give us $200 or this app will get exponentially tedious."
All the more reason MacOS > iOS.
It's not nerfing understand that mobile tech was horrible compared to what we have now. You seriously expecting a single core 800mhz 32bit processor and 256mb of RAM to run a modern OS. This is a thick minded, erm comment.
