Bandwidth, etc. may become too cheap to matter. The new iPhone has 300 megabit (peak; ideal) wireless capability. Comcast is promising to upgrade their entire network to 1-10 gigabit within three years without needing fibre to the home.
Come on smooth. You've been a serious programmer long enough to observe that demand for bandwidth and CPU fills up any new supply. If the new standard for bandwidth is 1000X greater, then users will be doing 1000X more microtransactions.
And you've been a serious programmer long enough to become very acquainted with the very important factor that big O algorithmic complexity drives your big wins in terms of performance and other attributes that hinge on it.
These are the sort of intuitive priorities that are just no brainer to any senior level programmer.
