Advice from one who thought the grass was greener.
Don't risk disappointment
Buy an iPhone, even if you have to wait for iP6.
I've never used an iPhone as a personal device, but I have a decent amount of experience with iOS with my two iPod touches and an iPad 3. I switched to Android from iOS and while Android is far from perfect, on balance I have been much happier with Android's many permutations than iOS's stifling walled garden.
Luckily, I got to experience other smartphone OSes, feature phone OSes, and PDA OSes prior to the launch of iOS and Android. Even after the launch of either OS, I continued to use other alternatives in addition to the two big dogs. Truthfully, I do my best not to fully wed myself into any specific ecosystem. I loathe vendor lock in.
Any reasonable user can make the switch to Android or really any other alternative mobile OS. Particular to Android, the flexibility of the OS and the breadth of supported devices means almost anyone can find something that fits their use well enough to be happy. While I've always found iOS and its many limitations more challenging to live with, all philosophical issues aside, even I could make the most of transitioning back to iOS as primary device.
