Aesthetics - I love the style. Rounded edges, with a metallic feel. It is appealing to my eyes.
Screen - I don't love the screen, but I don't find it to be a massive turn off either. Pentile isn't really an issue for me. I like it more than the OG droid, BUT less than pretty much every other manufacturers screen...
Hardware - No complaints, not super compelling, but not sluggish either...
Phone - including bluetooth & speakerphone usage - The two calls I have taken have been loud and crisp, but I haven't used bluetooth or speakerphone...
Overall User Interface (including Motoblur) - While better than the previous iterations of Motoblur, it still leaves something to be desired. I'd really like to find a way to get a rom on there...
Widgets - Some interesting stock widgets if I wanted to see what friends and acquaintances were doing 24/7
Signal quality (Compared to other devices) - Similar to my OG droid. When in 4g areas, no problems at all. In 3g areas, sometimes my data connections drop, but its not a huge deal.
GPS - Spot on, working as expected
Social Networking - The integration is cool, but again I don't want to auto upload to facebook or anything other social utility. I'm not particular either way about it...
Email/Calendar - It works as expected..
Battery Life - I got the extended battery, so I can go well past a day without charging.
Performance - Solid performance. Minimal hiccups.
Media (music, movies, DLNA) I haven't really gotten around to this part.
Keyboard's - Swapped stock for Swiftkey X and much happier
Camera (both still & video) - Stock still camera is terrible, but easily rectified by using a 3rd party which makes it into a much better still camera. Video software was much better executed...
How the Bionic compares to your previous smartphone (if applicable)
It was a massive upgrade from the Motorola Droid. Everything works better from the getgo...
Disappointments (if any)
The screen wasn't as compelling as I would have liked, but I knew that going in. Not a fan of the placement of the power button, but its not a deal breaker. Stock camera software is crap, much the same as the OGD. Too much verizon bloatware, I like some of the stuff like NFL mobile, but I'm not interested in VZW anything...
Overall: I like the phone. It nails the major functionality of a smartphone, but fails to execute on details. I wish Motorola would consider unlocking the Droid Bionic, so that users could more effectively control their experience, but that is much less a criticism of the Bionic than Motorola Mobility...
