How many laptops that can't read DVD's won't be woefully unpowered in every other way imaginable? I think my laptop is about 3.5 years old, and it has a combo (CD-RW and DVD-R) drive. It's a nice machine, and I'll keep it as long as I can (it has REAL serial and parallel ports, and can boot DOS off floppy; some bit-bang apps work faster under DOS than under Windows) but I don't think it'd be much good for the new OS.
What you say is 100% true but remember that Win95 came out on CD but on floppies too. About 16 of them. Those floppies were invaluable for laptop owners. Their laptops were likely under powered for Win95 way back when
