BlackBerry user of 7 years or so... pretty much have decided to go with Android. BUT I am stuck deciding between Nexus 6 or Note 4, or maybe Moto X 2014.
So, one thing I really like about the Note 4 is that it can take an SD card. And the S-Pen intrigues me. But how fast could I get Lollipop on it? I'd be somewhat willing to use "easy hackery" to get there.
As far as the Nexus 6; I like the idea wireless charging and stock non-bloated Android.
Moto X, pretty awesome and cheaper than the above? ...plus some cool Moto apps.
