Dick,
In my previous life I was a Sales & Marketing senior executive. We researched all the major CRM solutions. They all have strengths and weaknesses. One of the things they all have in common is that the learning curve is moderate to high, and the pay-off is high, PROVIDED that you use them for ALL your communicaitons. If you are not going to do that, stick with something like Outlook and the various add-ons that are available for it.
