If you were sharing what you think JC is smoking then a 300 Mb download should be done in the blink of an eye. Maybe Sony should bundle some of this "Magic mixture" with their consoles then they'd hear no complaints from anyone, in fact it could even help Sony outsell the XB 10 to 1.
I of course these days, I am a reformed, and have reverted back to an "unenlightened" redneck. Although I'd still like to point out, the s*** we used to smoke, actually made time almost stand still. The moral here is, in those days, a 300mb download would have taken forever, or certainly seemed like it. (Although you could alleviate some of the boredom by watching candles melt, and/or watching the light trails from the taillights of passing cars..

).
For all of you, an OS patch can't be compared with downloading a movie. First of all, there's Redbox, your first line of defense against the MPAA, and second, any type of imaging files are mostly to blame for the massive HDDs that all of us need these days. (The RAW files from my DSLRs range from 3 to 7MB, and they're ancient, puny, 10.2 MB sensors)
So, while you wouldn't get a whimper out of me to about having to download a 1GB scenery file, I'm going to keep bitching about a 300MB OS patch to get the console up and running correctly and fully functional. It should have been done before it ships.
Even M$ has more reasonable excuses for a zero day patch on a new OS. For example, "we couldn't test every program in the world for compatibility", or "that piece of malware didn't even exist.when we pressed the first run of discs".
