Jim I agree with you on a basic setup but if a system is engineered correctly, its very easy to have a balanced systems. The main benefit to a 300mW/400mW (soon) radio is a lower gain antenna thus a larger vertical beam width at the base station, this is NOT the best setup for all applications but it does add additional options to the WISP tool box.
Also aesthetics comes in to play many times where a small, clean looking device unit is the only option, again the radio gain can be the difference between a link working or not. Some of this may be outside the decision of this list but there are valid reasons for these designs.

The Prism cards will continue to become less of the equation with time. The Prism 2/2.5 chipset just costs too much to make it into any real 'volume' product, and there are other 'high power' solutions (on yes, Atheros and Realtek) chipsets, that, as David says, provide tx pwr ctl, as well as more interesting architectures for software tricks, equivalent or better receivers, etc. I'm not sure what the value of a 300 or 400mW AP is. The client almost certainly doesn't have that kind of tx power, so your link won't be reciprocal. Perhaps the application is a 25dBm (300mW) bridge but this would be limited to about 18dBi of antenna gain, and an additional dBi of gain. Since you can run an additional 6dBi of gain (on each end) with the lower power (23dBm) card, I would think that most people would employ the antenna, both for reasons of cost, as well as better rejection of off-axis interferers. obligatory disclosure: I sell a lot of high-power cards (as well as the other things mentioned here). Demarc is a competitor.
