I borrowed a BB z10 from a friend to see if I wanted to replace it my HTC 8x with it. I really enjoyed the new BB10 OS. It is really designed around productivity. The hardware was also very nice. I loved the BB hub that acts as a giant notification area. I found myself really missing my 8x. I missed my live tiles, Xbox music collection, the smoothness of the WP os, and the colors of WP8. So I switched back to my 8x.
In the end the main reason why I switched back was because the app ecosystem is horrible on BB10. It reminds me of the days when WP7 first released. Its that bad. Even though I loaded a few android apps on it. You don't get a complete experience because there native apps. They don't use the "flow" design language. Right now I can only support one underdog OS at a time. And for the time being WP8 is my choice. Love the hardware, love the software, love the whole design language and its really starting to pick up steam as the official 3rd choice OS.
