I understand digital is the wave of the future for our media needs, however I don't think we are quite ready for it. I currently have a 40/5 connection and it takes awhile (an hr or so) for me to download the free games that have been on Xbox live. One would assume the games for the newer consoles are going to be a tad larger. Take a game like Cod or BF, imagine what it will be like when there are tens of thousands of peeps trying to dl that content all at once on release day. I bet there will be some serious bottleneck problems or flat out server crashes. I have experienced that on just about every MMO I have played on the pc.
Second issue will be glitches. I have had a zune for many years and have lost many songs due to glitches or license issues only to have to rebuy them because MS no longer had the song with the same "drm" attached to it. That really sucks. Also, one hiccup on a long download, power hit/internet bump etc, and their is gonna be a corrupt file and will have to start the dl all over again.
Until we have a solid wide pipe(like google is currently doing), I thinks we should wait just a tad longer before we go all out.
