Just FYI to anyone thinking about upgrading to the 735 from the 928, I did it recently. I got the 928 shortly after it's release, even after the verizon rep tried pushing me towards andriod or apple. The 928 was(and still is) an excellent phone, I am so glad that I didn't listen to the people trying to push me towards other devices. My 928 still works great today, with the exception of the battery. I was going to take it apart to put another battery in, but decided I may want to upgrade, and keep my 928 as a back-up.
Recently, I tried to get a 735 from multiple verizon stores, but none of them had these phones in stock, and the sales people advised me against Windows phones. I bought a "new, out of box" phone, and decided to go the slow insider preview path with it. Other than the battery issues that I had with it a few days ago(I believe that is sorted out now), I REALLY like the 735. When the phone is on the charger, and I am working on my computer or tablet, I will get a notification that pops up when it is at 100%, and ready to be unplugged. Also, if I receive a text, it shows up on my computer or tablet, and I can reply directly, without touching the phone. Xbox achievements also pop up on my phone(faster than they pop up on the computer for some reason), which is also pretty cool.
On the down side, I really miss the camera button, and the picture quality is not as good on the 735. There are several apps that do not seem to be available for Windows Phone 10, that I had on my 928(ex: IMDB... I used that app a LOT). The internal memory is less than my 928 had, but the 735 has a microSD slot, which is nice. I also like how the 928 has the back button, windows button, and search at the bottom of the screen. You can get these to pop up on 735 with a swipe, and I am hoping that I will like it once I get used to it.
So basically I was reluctant in upgrading from my beloved 928, but I like a lot of the new features of the 735(and I am sure I missed a bunch of items). So far, I am really happy with my new phone, and glad that I stayed with a Windows device.
