It wouldn't be that hard for them to do it, probably cheaper too.
Not really. Everyone forgets that servers cost money, bandwidth costs money, spare parts for servers cost money, electricity costs money, a proper room with proper cooling for the servers costs money, technicians to keep the servers running properly cost money... There are plenty of costs that are happy to come in and take a share of the money saved by not printing and shipping physical copies.
Plus you don't really own digital copies, so you can't sell them when you're done and know you'll never play them again to get some money for new games. You can't loan them to a friend. You can't rent them. You're also at the mercy of the publisher or digital store owner as to if you can keep playing that game or not, they could just decide one day that hey we're taking this game down and you can't buy it anymore, and if you lost your copy you can't download a new one oh and of course, no refund.
Also, it's quite rare that downloading a full retail game is quicker than just going to the store and buying a disc. Say I want to play Killzone 3 on launch day, and Sony decides they are going to sell it on discs and on PSN. So I can either take 40 minutes to an hour to go to a store and get a copy, then start playing. Or I can get a download copy and not play for hours and hours as it downloads and installs (it'd be a miracle if you manage to play it on launch day at all; between the fact that it'd be a huge file, Sony's normally slow download speeds, and the fact that so many other people would be online to either play or download their own copies, it is going to be one veeeeeeery slow download).
Oh and of course, not everyone has decent internet speeds, so a lot of gamers would be screwed without physical copies to purchase. Or maybe they have bandwidth limits, or some other barrier in the way that doesn't exist when you just go down to the store and pick up a disc.
So if games went download only, I would be quite upset to say the least. Lots of downsides, very few upsides. In fact, the only thing I think is great about digital copies of full games is for portable systems, as it means you can just keep your games on the device's memory or a memory card and carry only the device instead of the device and a case full of games.
