Having had a Droid Razr for a couple of years, followed by the vastly improved RazrMaxxHD for another couple of years, I'm used to the top button turning the screen on, the button underneath for volume. What possessed Motorola to have two volume buttons at the top, and the turn on button underneath is a mystery to me. Taking awhile but I'm getting used to it, even an old dog can sometimes learn new tricks.
How slippery the 'wood' back plate is. When I first bought the phone (at the store) they were out of the leather back plate, so I opted for an Evo Check case protector. Fits well, very grippy, and the plug for the charger fit after the rubber stretched a bit. To begin with I had to undo the bottom of the case to plug in the charger, but that resolved itself within a few days. The edges of the glass are protected as the Evo Check wraps over them a bit. Even though the glass is guaranteed against breakage for 4 years, an ounce of prevention is worth a pound of cure.
The volume could be better on calls. I find I have to use the speaker phone, as I did on the two razrs that preceded this device. Overall I'm very happy with it. Wider and taller than the razr maxx, but the larger view, larger keyboard, make up for that , and I've already gotten used to the size.
