I took flyingred's comment a bit different than Thom (i.e., not related to manufacturers letting customers be beta testers, which I think is a valid point).
I believe that (some) manufacturers design the very best product they can. Unfortunately, sometimes the price turns out to be higher than a market can support. Therefore, perhaps they trim some areas that will enable them to lower the price and give up a bit of performance.
Perhaps, then, the manufacturer offers the full-blown system with the "best" power supply... but then if you can't quite afford that (or think it doesn't matter), you have the option of getting the table with the lesser power supply -- and maybe getting 95% of the way there with the ability to upgrade later on. I.e., you won't have to settle for a maxed out but "lesser" overall design (lesser TT + lesser power supply), you can get the better TT + lesser power supply.
This is all irrelevant if the power supply in question was designed purely in response to customer issues/problems -- I'm not familiar with the DPS power supply.
Also, sometimes new manufacturing options become available with the passage of time, so it's not necessarily a conspiracy (and it's tough for me to say that as I am a HUGE skeptic myself).
