I feel that a lot of people are putting their faith in the usb-thing right now. In one week it all exploded and staying on loadiine is almost (almost!!!!!) considered to be the stupid thing to do :-)
Games installed with fake tickets which are probably still there even after removing the game, what happens if Nintendo pushes out their final firmware? Of Nintendo somehow detects fake tickets and bans your console?
I guess at the end only future will tell how good or bad it all turns out. If it all turns out for the better I will have time enough to install some games with this method.
For the time being I will use loadiine. With the games I play I don't see any lag, loadtime or compatibility issues so why bother :-)
Just my two cents
