Hmmm... (possible) reasons why the PSP isn't the "de facto" portable media device:
1) Playable formats - poor. It plays mpeg4... kind of... and there have been resolution issues for quite awhile that only
might have been fixed now with a recent firmware update. Maybe. It doesn't play most formats "natively" and requires fiddling with on a PC (either through a disc you have to buy from Sony, or some 3rd party programs you have to find out on the net). It's just not user-friendly nor intuitive. [This is the biggie reason, IMO.]
2) Kind of big. Some people might not like the size of it compared to the Ipod. *shrug*
3) Have to purchase storage cards (comparatively expensive Memory Stick storage cards at that) to actually hold your data (as opposed to having a built-in HDD).
4) Competing products. The Ipod has Itunes - a nice website with lots of stuff available all ready to go for your Ipod. Done and done.
5) PSP Price - if #1 above sucks (and it does), then the PSP is too expensive for those who care about portable media and not games.
6) UMD price. Way too expensive for what they are (PSP-only, no special features). They might have been popular if they sold for a quarter of their price ($4.99 or so).
7) Battery life - comparatively short.
Disclaimer:
The above are possible reasons why the PSP isn't the optimal device for portable media - they are not exhaustive, nor may they be entirely accurate as seen by the general population.

You're trying to make some point about market penetration, which isn't germaine to the topic of how the PSP performs as a multimedia device compared to other such devices. What most people do isn't a compelling agruement for that topic. Maybe they lug around laptops on their trips. Maybe most people make poorly-informed decisions. I hear that betamax was actually superior to VHS.
Didn't you ask why the PSP wasn't the "de facto" portable media device? What do you mean by that? Maybe it is. How do you know it isn't? If consumer perception has nothing to do with the equation, then maybe the PSP really is the actual best portable device out there (and the original premise of this entire thread is flawed). Could you explain more clearly what you mean in you OP?
P.S.
What
is the current "de facto" portable media device right now, and why?
