I want to make my vote clear.
I voted "other", but that "other" really is the "This poll is stupid" option.
You are not forced to upgrade. You are also not forced to hang on to a 3 year old device. New software = new features, generally new features require more power because they do more.
People who are upset by this are upset at the speed at which the industry moves, not Apple specifically.
I'd much rather be pushed forward than held back. If one upgrades every two years, one would never run into the issue of having a device "slowed down" by an iOS update.
I wonder whats makes ios8 so resources hungry, there are really no significant improvements to justify the loss of smothness
Ok, I can live with a poor optimized system, but at the same time there should be an open door to let the "power users" to downgrade, just as with Android, PC or even Mac
