Like with ANY phone it will be hit or miss. For example you enjoy your droid bionic, but other people would beg to differ. I enjoy my Nexus and have had no real problems with it. Other people are having problems with theirs.
I absolutely love my nexus. I've had it for about 5 weeks now and am completley satisfied. Some people say they have connection issues, reboots and the such. Like tidbits mentioned above, it is hit and miss with every phone, but I say if you want the biggest bang as far as a phone goes, the Nexus is it
