Disk drive's higher price than the computer itself
I noted in mid 1980s the disk drive becomes popular to North-America even if it costs more than the computer itself
If you think the disk drive at $249 is expensive, take a look when the Commodore 64 is introduced in 1982.
Commodore 64 is at $599.00 and the disk drive at $399.95
The computer is more expensive than the disk drive.
At $249, I would buy a disk drive.
I wonder how much a disk drive is in Europe since people keep buying cassette games.
