I have had mine almost since they came out. This is the first one I have not rooted. I left it stock and just got the updates as they were pushed out. I have only had to do a battery pull a few times since owning it and I wasn't forced to just did to see if an issue may or may not go away.
The phone has been great. There has been just a few times were it seemed sluggish and the battery does not typically last more than 12 hours but that is workable. It seems to do what most of the new phones do with out to much problem. My wife just traded her Droid X for an Iphone 5. The 5 is faster than the Bionic and has a more vibrant screen. But most of the newer phones have a more vibrant screen than the bionic. There are things the iphone will not do that she misses on her X.
I will be upgrading in June but not sure what I will get yet. Samsung, Motorola, or Iphone are tops on the list right now. Any thoughts?
