The combination of buttons pushed to process a hard reset is still software dependent. If the software is totally screwed up, it might not work. I know two people who have had to take their iPhones into a store to have the battery removed to restart their iPhones. So, there is a difference. (I have had to do that to a Toshiba Laptop I used to own a few times. Holding the button in for ten seconds is supposed to do a hard reset, but a few times, I have had to remove the battery. The software was the problem.)
However, it appears that the Razr's battery can be removed and it should not take that much time to do so if required.
I am not condemning the Razr for this failure to allow the battery to be removed. So far, I have not read of anyone having to take their Razr back due to it being totally locked up. Then again, probably only (max) five percent of people who own phones come to forums. In fact, my browsing of these forums the past few months has been to decide what phone to get if I do get a new phone, and I have narrowed it down from three (Nexus, Rezound, Razr) to two (Rezound, Razr) and if I was to make a decision today it would be the Razr.
I'm just noting that there is a difference between a software dependent "battery pull," and an actual removal of the power source by manual means.
