[quote name='gunm']I'm referring to lack of proper web integration a la XBL.
I want to be able to start a download, add credit or purchase things from PSN while I'm away from home via an Internet capable PC. As far as I know, Sony hasn't gotten around to doing that yet.
Amazon's system is just to generate a code which you need to add via the Account Management screen of your PS3 or PSP.[/QUOTE]
The REAL feature would be to allow remote start of PS3. (much like the way you can do it via your PSP) Not necessarily full-featured, but say, if I start up Media Go from my laptop while I'm away from home, allow me to "remote download" on my PS3. Utilize idle bandwidth at home, plus it'll be ready by the time I get home, to load onto my PSP, or install on PS3.
True, if you had Media Go, you could in theory download it on the spot, but a)that would work ONLY for PSP and NOT for PS3, b)what about situations where you're on the go/don't have a constant internet connection (i.e. in a Starbucks for 5 minutes, but not long enough for a full download), and c)if you're on a laptop without a power cord, you might not want downloads to throttle the bandwidth and reduce battery life...
I think if they implemented this kind of system, like you alluded to, Sony's PSN integration would be in much better shape. Especially if I could see (and easily navigate) a download history to re-download old PSP titles, etc. if I deleted them to make room for something else.
