I use to be a huge android/google guy as far back as I was in one of the first invite groups for gmail when it was beta, had google voice before google owned it (grand central it was called) and so forth. When I got my iPhone 5s I fell in love with the apple system. I now use gmail and have my google voice number but I have everything synced cross platform. I can put an entry on my MyBP calendar and it not only syncs to my phone but also I have it all syncing to my google calendar. My gmail is through the gmail app and have all the other google apps on my phone. I use google maps over apple maps usually
Having said that, I have no desire to use android any further. I have an android as a back up phone but I like aplle devices and MacBooks. I love how I can sync things from phone to computer so easy, love how when I copy text on the MBP or iPhone I can paste it on another device.
I have went as far as buying all of my kids iPhones, two of my kids live out of state and we FaceTime quite a bit.
I like how google apps work but like using an iPhone
