My "twisting in the wind" on buying a 2600 or a 2400 really came down as to the key board I was most comfortable with.As my computor and I have at best an uneasy relationship,I opted for the more comfortable floppy disksystem of the 2400.I guess it's hard to teach an old dog new technology.Many thanks to Greg, Velt8 and Ken for their advice.
