I would like to propose that next release the full OS developement environment on CD-ROM. Since CD-ROM drives can be had <$400 and the mastering cost is very low for the media a cd-rom should only add a small amount to the cost. I would like to see the Installer understand and support installation from cd-rom. I would also like to have the ability to launch Apps from the cdrom. I think this offers several advantages, such as: 1) It allows users purchasing the 105 and 200 MB models to customize their software environment to their needs. For example I would like to propose to our CMSC department we recommend the purchase of NeXT machines to CS undergrads; however the cost effective machines (the 105 or 200MB models) don't have the software development environment loaded on them, thereby rendering them somewhat useless to a CS student. 2) Launching applications from the CD-ROM would be slow; however I would rather have a slow application then not have the application to begin with. In addition, once the application is loaded into memory the speed would be the same as users now experience. 3) It provides a backup of the OS software that presently is not available. It bothers me to recommend a machine to students where one command "rm -R / " can cause them to lose all their software. Making a backup of the slab (or the heaven forbid the 400MB model) to floppy is somewhat unreasonable to expect of students. Having a CD-ROM distribution would allow someone to re-install the system software off the CD-ROM, eliminating the need to backup the OS software. This would mean that users are only responsible for backing up their specific user files. 4) Having the cd-rom distribution provides a level of security some sites require. With the cd-rom distribution you can perform a checksum on selected files on your hard disk and verify they are the same as the CD distribution. 5) Using CD-ROM would allow Next to more easily update the OS and Apps. Every couple of months NeXT could release an update Cd-ROM with fixes that user sites could install. 6) Releasing the OS on CD-ROM would promote sales of Cd-ROM drives. As more users had cd-rom drives I think you would begin to see more applications available on cd-rom. Specifically, I am thinking of large text or multi- media datasets being released that could be accessed through the librarian or other Apps'. 7) Finally, if NeXT would work with Transarc and get a server version of AFS (Andrew File System) working the performance of the 105MB machines using cd-rom as their operating system would be pretty good. What I envision is allocating the 105mb drive as 20mb for swap, 40MB to AFS, and 45MB for user files. As files are accessed on the cd-rom they would be cached by AFS on the hard disk. With this model, you could have the complete software release, resonable performance and 45MB of user space on a machine that would cost about $3600 (105MB version + cost of a cd-rom). My question is, do others agree with me that cd-rom would work or am I mistaken and should I change my views? If I am right, how do we voice our views to NeXT.
