I continue to use ECCO because it has a calendar and an addressbook, which function well enough, although I don't really like either one very much. I have tabs for the main areas of my work, which contain note info, but also action items. What's important for me is the ability to have the calendar as part of a view with the tabs I use, permitting me to drag items onto the calendar or to do list area. The ability to visualize this information is very helpful in planning and organizing.
I could make the SN grids work for me, although Ecco's ability to have multiselect items may not be manageable with the current grid control. Once Pierre can get the calendar up and running, I'd switch over in a heartbeat. It's just too inconvenient to have my calendar in one application and the rest in another or others. The planning becomes fragmented and inefficient.
I've donated cash to the cause, because I have faith in Pierre, I've tried and/or owned many of the PIM's and notetaking packages discussed on this forum and a couple of others - DonationCoder and Outlinersoftware. I tend to keep coming back to Ecco, even though it's dated, because the planning and organization don't feel fragmented. When Pierre gets SN off the ground with a calendar, I'll set Ecco aside.
