It does have the "1024 cylinders" problem though.

As I understand it, (at least with DOS/windows/OS2), you can only "see" one
primary partition _per disk_. This was also what various HOWTO's seemed to
say.
The fact that windows (95 and NT) cannot use partitions properly - they
*require* that they are on the first primary partition on a disk - means
that partitioning is _alot_ of hard work (trust me - I've spent a week
reinstalling things and messing around).
One feature I look for in a design is easy modification in the future (which
is normally always needed for one reason or another). Most things "designed"
by MS or to do with an IBM-PC are not. This ain't a flame - it's just fact:
- BIOS date problems - compared with Unix which will eventually hit a
problem 60 years after it's "birth)
- IRQ cascading
- only now going 32-bit (cf Mac/Atari/Amiga - 32/16bit since introduction)
- FAT filesystem
- VFAT (and even NTFS IIRC) - upper/lower case confusion
- allowing spaces in filename - *completely* *braindead*
....
The PC wasn't badly designed - it just wasn't designed.
