That would be great...
I hope that apple will do away with optical drives soon, and release software via dl or usb/sd cards in the near future. Although optical media is very cheap, it is such an outdated and unreliable delivery method. I've had two Apple notebook Superdrives crap out within a year of use, and I am not alone. The lack of reliabilty is well known in the Apple community.
My hope is that Apple is considering more advanced delivery methods for future notebook revisions. I think the result may represent a better user experience for us, and potentially less cost for Apple, warranty repairs, replacements, cost of media...etc.
