My first attempt to leave iPhone was a move to the Sony Xperia play. It could have been a great phone, but the Sony ecosystem is very different that Apple. You had to purchase everything several times. Oh, you want that movie on your PS3 cash please… Now you want it on your Sony phone, more cash please… now you want to watch in on a computer, more cash again.
The Samsung phone has worked quite well for the past few months. Some things are still unclear (like where and when photos are shared) and there are a few apps I haven’t re-purchased from Google Play simply because I have them on my iPad.
Weirdly enough I’ve stopped using the iPad a lot as well. The larger format phone is enough for reading and note taking.
