I don't know about other people, but personally, I hate CDs, DVDs, and even Blu-Ray. USB sticks are the future. In my opinion, someone (SanDisk I hope) should make a limited-usage or one-time usage USB stick that effectively replaces an optical Disk.
So basically, instead of selling a huge CD and box, etc. Just a small USB stick would be needed, since the majority of computers nowadays have USB 2.0, but not all computers have an optical drive. Netbooks, Nettops, and cloud computing are the future. Read speeds would be a lot higher than on CDs or DVDs, although the price is a bit higher compared to optical disks. Basically, in comparison:
Benefits of Limited-Use USB sticks:
1) Smaller size.
2) Faster read times. (And even potentially faster once USB 3.0 comes out).
3) No Scratches to worry about.
4) No optical drives to worry about. (Maintenance, power, newest technology (blu-ray, for example), internal space)
5) Less power required/More efficent.
6) Multiple USB sticks possible.
Benefits of Optical Drives:
2) Industry Standard
Basically, my perfect "Software Installation Process" would either be downloaded, or Via this USB stick idea. Also, the USB sticks could potentially have a female and male connector, so that multiple USB sticks could be plugged into each other, and locked so they wouldn't be lost. Much easier than dealing with optical disks and worrying if they will get scratched.
I just wish there was a way to tell the company some suggestions!
