Why doesn't Apple ship machines with the 2.88MB floppies that are used
in the NeXT?

Reply:

The NeXT drives are constant rpm (MFM) types.  The older apple drives,
400 & 800K, used a varible speed mechanism (GCR format).  To get to 1.44MB,
apple came up with the FDHD drive, which reads both MFM and GCR (apple
1.44 meg floppies are MFM).  Apple certainly could put a 2.88 meg floppy
in one of their computers, but it would not be able to read the older
floppies (400 & 800).  That's why the NeXT as of yet, cannot read any
mac floppies other than the 1.44 meg. That's why you should be wary of
cheap aftermarket "superdrives" some of them can only read the 1.44 meg.

Of course, I could be wrong :-)
