Lion should really be on a disc, and this is why i think so: Lets say something goes horribly wrong and i have to reinstall my OS. It happens to the best of us. Instead of popping in my Lion disc and installing like normal i'll have to... 1) Install Snow Leopard 2) update to the newest 1.6.X if my disc version is before the App Store was introduced. 3) Download Lion (~an hour depending on one's connection) 4) Install Lion 5) Update Lion This could take a large part of your afternoon. If there were a disc i'd simply: 1) Install Lion 2) Update Lion and be done in an hour or so. I suppose for people who have full Time-Machine backups they could just restore and keep going, but i find that backing up everything wastes space so i just back up personal files and media. Anyway, thats just my thoughts on it, flame away.
