Well, +Jacob Jacobs
it's really not that easy. A lot of android users are android users because they do prefer to have choices. They want to be able to customize their phones, they want to tinker around.
It muss be very frustrating if you've got your eye on a particular phone, but the carrier of your choice has already messed around with the software. Here in Germany, there are hardly any phones with sim-lock being sold, because the public just will not except it. In America the carrier thing seems so messy and sometimes complicated (not to talk about expensive) this is killing innovation and phone users have to bail it out.
