i thought the razr died ..... like ... 5 years ago.
just joking !!!!! my wife loved her (my old) razr so much that she had the same one for around 3 years until she ruined it in a hot tub. i'm glad she did because i pawned off my omnia on her and got a droid. you'll notice the light will be red when you're low on battery and blue if you use twidroid. i think you can customize the colors.
anyway, you've basically lost your trek communicator and gained the enterprise. oh, and go ahead and download the free tricorder app. it might be the single coolest app that you don't need. i'm saying this supposing you're a fan based on calling your razr the Star Trek communicator. it has tons of real time actual functionality
