Among its many other features, Ecco Pro installed an icon (the "Shooter") into other programs so that you can add text highlighted in the other program to your Ecco Pro outline. And better yet, the information stored in Ecco Pro could be synchronized with the then nearly ubiquitous PalmPilot hardware PIMs.

The demise of Ecco Pro was blamed by many (including the publishers of Ecco Pro themselves) on Microsoft's decision to bundle Outlook with Office at no extra charge. And while that was undoubtedly part of the problem, Ecco Pro also failed by marketing itself as merely a fancy PIM to lawyers and others then lacking technological sophistication sufficient to permit them to appreciate that the value and functionality of the product went so far beyond that of supposedly "free" Outlook that the two might as well have originated on different planets.

Jeff Sonnabend in the Ecco Yahoo forum: "I remember first trying to learn Ecco 1.0. It was tough until the proverbial light went on. Then it all made sense. For me, it was simply understanding that Ecco is just a data base. So called folders are nothing more than fields in a flat-file table (like a spreadsheet). The rest is interface and implementation of various users' work or management systems in Ecco. That learning curve, to me, is the primary Ecco "weakness", at least as far as new users go."

Chris Thompson: "If your goals in using a PIM are mostly calendaring, todos, and a phonebook, then Maximizer, Outlook, and Time and Chaos all do a reasonable job. On an enterprise-level, Lotus Notes would be another good choice. If you're more interested in keeping track of notes or research, Lotus Agenda, Zoot, or InfoHandler are better choices. For keeping track of miscellaneous files, InfoSelect is pretty good. On the other hand, if you want to do a little of everything, and do it well, Ecco really has no rivals."

One fundamental issue with Ecco Pro I gleaned from the many phone calls I answered from customers was that people didn’t really know who the product was for. Sales people wanted to use it as a contact manager. Small business owners wanted to use it as a database. Home users wanted to use it to make to-do lists and track appointments. The problem was that it tried to be all those things at once. As a consequence, it did none of them very well. The product was bloated with features and extremely difficult to use. Even seasoned users did not understand its advanced functionality very well. After a year and a half as a phone rep, I still couldn’t offer a good explanation as to who the product was for.
