Physical VS Digital

[Kriven]

in terms of convenience, that's correct (though steam is far, far above xbla there)

but still, there's not avoiding the fact that one day, all DD services will eventually go down.
All those games you paid for? No more.
That doesn't happen with physical copies.

Since I'm not streaming the games and they're actually on my 360's HDD, even if the XBLA service shuts off, I have what I purchased so long as I can take care of my 360.

And there's really no reason DD services will shut down. At least, not within our lifetimes. So long as we have the resources required to keep the technology running, there's literally no reason for these services to shut down if they're still making sufficient income.
