I am starting to get used to Android ...
I have been using a Nexus 4 for a bit over a month. I am finally getting used to it. Overall, I still think the iPhone is a better experience, BUT, there are two bits that Android has that I can't duplicate on an iPhone (to my knowledge):
1. Divide ... this is an app that sets up a virtual machine like instance that allows me to separate my personal "phone" from my "work" phone. I can switch between the two with two taps of the home button. I find this to be a huge improvement to the direct integration of a corporate Exchange account offered in both the iPhone and native Android OSs.
2. DND Call Blocker ... somehow, my cell number became a target of phone spammers. On a single day (before I installed this app), I got 20 spam phone calls. With DND, I have specified that I only want callers on my contact list to ring through ... everyone else goes to voicemail immediately.
After using these apps for a while, I am not sure that I can go back to an iPhone without them ... I could maybe deal without having Divide, but I can't stand the idea of getting pounded by the SPAM phone calls.
