A numeric keypad (the number keys clustered together as they are on a calculator) is useful for anyone entering large amounts of numeric data, but this feature was lacking on the Commodore 64. Since many Commodore 64 owners spent hours entering machine language programs in the form of long lists of numbers, this feature was often asked for.
...they make the C128 more attractive to those established business software developers who are used to working with more traditional keyboard arrangements.

I well tell you, okay? Take the C64, slap another 64K of bank-switched memory into it and squeeze it into a sexy case. Improve the keyboard by arranging it into a Selectric-style layout and bettering its feel. Take the excellent Basic from the Plus 4 and build it into the new "C128," adding special sprite and SID commands as in Simon's Basic. Keep the directional cursor keys and function keys across the top, as well as the built-in machine language monitor. Return to the port configurations of the past. Make sure all the machine language disks and ROM cartridges designed for the 64 run beautifully on the C128. And price it at $400 list.

One would hope that Commodore will soon come to their senses and put out a `64/Plus' with such selling features as 128K of memory, 80 column display option, a better disk drive, and most importantly, complete compatibility with C-64 software and hardware

For one thing, BIOS source code is available, but not available for the BDOS or CCP.
