Let's compare with the other major system that's designed to grab data, like demos and movies, off the internets, the Xbox 360. You know how many games have demos on Xbox Live? FIFTY FIVE. That's right, 50 and then 5 more. There are even multiple demos for some games, for the demo-downloading completist.
I realize Sony's been a little busy screwing up its PlayStation 3 launch, but surely they can put some dedicated people on the PSP side of things and leave them there with resources to help the system live up to its potential. Right?
I will give Sony this, however: the ability to connect to your PlayStation 3 via your PSP from anywhere you have a network connection is pretty awesome. I haven't seen it in practice yet, but the idea is really quite intriguing. It is precisely the kind of feature Sony needs to one-up Xbox Live. Since Sony has the dedicated handheld platform to built upon, it is playing to a strength that Microsoft doesn't have (yet).
* I should note that I think there are five demos. I can't get my PSP online in my current location to double check. Corrections in the comments, por favor.
** Yes, I can download some unofficially and install them. Most are in Japanese.
I found this site which usefully puts all the demos available in one place. There are about 24 in total, but a large proportion are Loco Roco demos in various languages.
