Seems like there are a lot of us that have left Android and returned back. I really think Android is taking the lead on the mobile market now. To a certain extent, I did not think that I would stay with Android after being stung with the S3. I loved the S3, just hated the battery life. It got to the point where notifications had to all be switched off to make it through 8 hours.
For me, the Edge was a lower risk and I know that some will disagree and that is fine. Also, the Note 3 was the first phone that I actually considered keeping past the 12 month mark. I find myself using my tablet much less now, that I have the larger screen in my Note 3. Btw, I had an Ipad 2 and gave that to my dad and bought a Galaxy Tab S. That tablet display is incredible. I probably would have stayed with the Samsung product line if it hadn't been a desire to shop around and try other devices. If the Nexus doesn't work out for me, I can always go back to the Note line with the Note 4.
Another cool thing too, is the wearable market. I am a watch kind of person before the Note 3. I got the Galaxy Gear on a promo with the Note 3 when I bought it. Never wore another watch after that. Do not think I will ever go back to watch. As a matter of fact, I just ordered my Moto 360 today.
