I was doubtful about the Razr, but this thing is badass!!! The screen quality, button location, sound, and speed is grade A! Comparing to the nexus its not as good, but pretty close.
The Nexus has a bigger screen size when browsing and watching videos.
You cant tell any real difference in speed
The Nexus is bulkier (of course when compared to a razr)
The Razr takes clearer pictures and videos
Razr has hdmi
The resolution on both phones will make you drool.. This is coming from someone that owns a Charge.
Razr has audio visual control and transport to use with laptops, for presentations, etc.
Having ice cream sandwich is what puts the Nexus ahead for sure. Look it up if you dont know why ( too much to type lol)
The Nexus memory is not removable
Last but not least... Razr = Bloatware
Im personally getting the razor as its better equipted for what I need for work. Both phones are awesome and best in class. The only thing that scares me is the non removable battery on the razr. Could come back to bite me in the ass if its not a high quality like apple batteries... Plus no hard resets.
