@qisdtech I noticed a difference in signal strength especially with WiFi. When I pull up to my house I had 2-3 bars for the WiFi signal with the RMHD, now I get 3-4 with the DM. I am very happy with the upgrade, and I am loving this device! The only disappointment so far is the Assist app. I used to be able to make things happen by location, on the DM currently they only give you three options and it does not go as deep as the Smart Actions did. I had my phone set up to be silent when I walked into church and now I can't make that happen with Assist, although I haven't tried the putting it in my calendar as a meeting appointment yet.... Motorola connect is very cool which lets you do texting while at your desk so you don't have to pick up the phone. The phone is very quick no lagging and Google music doesn't skip anymore at least so far.
