B. Root, modify, tinker with my Note to have a kick a$$ phone.
For most of us Android users who have been around since the G1, and HTC Magic days; this is exactly what I love about Android. I can modify, or change what I want to make my device better.
Don't like the launcher? or how it looks? Use a third party launcher, change, and customize anything you want.
Don't like any of the stock apps? including the dialer, and messaging apps. You can change those too.
Stock keyboard doesn't have enough features? The Market has everything from Swype, Swiftkey, and even T9 keyboards.
Battery life getting you down? Root the phone, flash a custom rom, and undervolt the kernel. Alternatively, you can buy an extended battery, or a spare and switch it out when you're running low on power.
You can virtually change anything on your device, and that's exactly what I love about it. It's your phone, you choose what features you want it to have. I love the fact that most Android devices don't come with everything preinstalled. You can decide what apps you use most, or decide for yourself on how you want the device to work. Most of the time stock apps will suffice, but since Android is about having the freedom of doing what you want, the most rich, feature filled apps aren't going to come preinstalled on the device. Something that may be considered bloat to you, might be something that I absolutely need to have.
Android phones are definitely for people who love to tinker, and customize things.
I just thought I would add that I would still recommend an iPhone to an older person, unless they have trouble reading smaller print. iPhones are great for people that are unfamiliar with technology. Most of them need features that are obvious to them, most people aren't like us geeks. Some people need to be guided through the process, and we all know that besides (4.0 ICS, which is much more user friendly from using it on my Nexus S.) Android can be very complicated. It's definitely not the right OS for everyone, get what you need and be happy with it.
