Although Amazon and Steam both sell games it is a totally different market, Amazon I buy and the disk is delivered to my house in a few days - Steam I click a button and depending on the size of the game and my internet speed it is available between a few minutes and a few hours - Amazon the disk can scratch, break, get lost - Steam it is always in my available list when I log in, even after a reformat, new PC, friends house, etc. As far as service goes Steam is offering more benefits, especially as you can always go into offline mode and play without being connected to the internet for either LAN multiplayer or single player and if re-downloading all your games again is a ball-ache if you do trash your PC, your games folder can be backed up and just copied over again, all it needs to do is authenticate what you have is what you bought and no other downloading required. Amazon may well be pissed at being competed with, but they had the opportunity to invest heavily in digital distribution instead of being a massive mail-order warehouse for physical products, but they didn't. So strictly speaking it is Amazon that is encroaching on Steam's market. There will always be people that want to buy a physical copy and they will always be able to sell it as long as it is available, but they see physical media dying a slow death so either provide a better digital distribution method or you don't get my business. Wouldn't take a lot of effort to convert a warehouse into a datacentre, just be wary of making another "Origin" or it will be a massive fail.
