I bought Photoshops CS3 a while ago for my office and have been using it on those desktops for a while. However, I am trying to get CS3 onto my new laptop that doesn't have a disk drive. Is there any way to install CS3 without a disk drive? And even if I had one, would CS3 still be supported on a piece of technology this new?

Your quite lucky CS2 would not have run on a Mac today, but CS3 should be fine on Macs and Windows. You won't of course have access to the latest version of Camera Raw though.
