Am getting the razr m as I can't pass up the $.01 price for it from amazon. A few questions though. how is the battery on the m and signal? Will it be as good as my thunderbolt and make me forget about my thunderbolt? I haven't found one yet that has the battery life and signal of the thunderbolt plus durability. Most I am guarding with my life whereas if I drop my thunderbolt it may fall apart but it comes back almost unscathed.
