I'll add one thing to this. I've helped a few that have switched to Android set up everything and the biggest thing that most run into is the switch from iMessage to standard SMS. This is especially true when you have more than one Apple product. What happens is that when you switch, your iOS friends try sending you a text and you never get it. Unless you get on something that has iMessage. The solution is to go into all your iOS devices or on OSX and make sure you delete your phone number from the "receive from" section. That way Apple servers know you're not using iMessage for that phone number.
If you're selling an iOS device you should log out of all your accounts BEFORE erasing the device back to stock for sell. This ensure that's that your messages will be delivered to your new Android device.
The above-above post of yours is only 50% true. For me anyways!
You're special Del . You carry more than one OS around with you I believe so , yes, it most likely isn't an issue for you. You can leave your number associated with iMessage. You'll get your messages no matter what the sender is using.
Imessage switch to BBM its on both OS's All these helps and how too's but truly the biggest issue will more likely be using the different OS, getting used to the different keyboard sensitivity, complaining about the different GUI between the same Apps on the different systems. Ok for you guys out there commenting here who are experts and like to change around, but the average Joe, more likely stays with the phone specifically because they are used to it, comfortable with it, it does what they want it to, then they go out and change and don't like the new system it doesn't sit well with what they are used to. I am sure this is how the big Cell companies make their profit by charging restocking fees to all the people that try something new and in the end cannot get used to it.
I like the Nokia 1020 but still covet my wife's Q10 for some of the functionality!
