Companies don’t usually relocate just because it’s a little cheaper to rent/buy. If that’s the case, they all would move to the mid-west already. QCOM is well established in Sorrento Valley. They’re not going anywhere. As we speak, they’re taking over other company’s building in Sorrento Valley and make it their own as well as building more in Sorrento Valley. Other companies who are in CDMA business won’t be moving to far from QCOM either. Also, when a large corp move, they will have to consider the cost of the move as well as the possibility of losing some key employees if the new place will be too far from where they live.
