One thing I forgot.  My mom uses her C128 as a Midi sequencer, data base
manager, and store display in the music store she works in.  The data base
program she uses is called Perfect Filer, which, while not as powerful as
SuperBase, does a respectable job of managing her files of keyboard 
students.  

If you want the details on why a C128 can come close to and sometimes
even beat a basic PC clone, here they are.  The C128 in 2.04 MHz mode
completes 1 memory cycle (reading or writing one byte in memory) in
490 nanoseconds, a standard PC clone running at 4.77 MHz  completes 1
memory cycle (reading or writing one byte in memory) in 839 nanoseconds.
Both machines are 8 bit machines, from a hardware point of view.  The
extra speed in some cases of the PC is that the PCs 8088 processor
contains more registers (translates to fewer memory accessess, register
operations are always faster), contains a 16 bit ALU (16 bit math is
built in, versus programmed in a routine as on the C128's 8502), and
the 8088 has built-in memory banking, versus external banking, so
memory management on the PC can be faster, and can address more memory.
PC disk access is faster because the PC uses a processor controlled
parallel drive, versus the serially accessed drive on the C128.
