BB use to get great battery life, for me, back in HS/Right after HS but what apps did they offer that's consuming battery? All they had was twitter and Facebook. I won't get into how boring, simple and crappy the apps were. I'd rather enjoy my phone and my "wall hugging" ways (that I didn't know I had).

In defense of BBRY, comparing batteries and apps now that BB10 is running OS 10.2.1 is a loss for Apple. But please read on as I'm iPhone 5s user with a lot of BBRY experience I'm just sharing.
The Z10 battery is1800mAh, the Q10 is 2100mAh, and the Z30 is 2880mAh. The iPhone 5s battery is 1440mAh. Now yes, size isn't as important as amount of use. But bottom line if you did the same type and amount of usage on the iPhone 5s versus any BB10 device, there is no comparison when it comes to battery life. BlackBerry wins.
As for apps, with 10.2.1 you can download the Amazon Store and/or Snap. Thus you have direct download access to almost all Android Apps.
Now here's where I stand. My personal device is an iPhone 5s and it's definitely my choice for my personal device. However, I have a work issued BBRY Q10 on BES run through an IT admin. It's definitely my work phone of choice. If I got 150 emails, 300 texts, etc on the iPhone I'd be charging it by noon. The Q10 last from 5:30am to 11:00pm and still has 20% life left.
It's simply a matter of preference depending on what you need your device for. As for these CEO's bantering back and forth publicly, it's ridiculous.
Hopefully, nobody takes this message as a shot at the iPhone as I'm user. I'm merely providing my honest assessment because I believe both iPhone and BlackBerry 10 are great.
