I’m expecting the new iPhone release this fall to be coupled with some great version of Siri/model. This could be the first reason I’ve seen to upgrade in a while (although even that I’m not sure of, as I am king of in the “always use the best model it’s worth it” camp.)

Apple has a great shot at making a highly optimized 4.5 version of this model highly tuned to the next gen iPhone, which could work great.
