Mostly, I use Linkman for freeform stuff, pointing me to web links with keywords. However when I write and organize I usually want a simple explorer-style hierarchial notepad, preferably with tabs (tabs basically mean I do not have to open a different file or have long involved left side explorer looks ... it is simply an organizational dimension). Good RTF is essential. Stability too. Everything else is negotiable. Multi-folder-level comes in handy, 2 levels might be sufficienct.
Keynote I traditionally used. Keynote-NF remains in the running.
TreenoteDB has a nicer look-and-feel, but they have a funny concept of "Free" where you really need "Free-registered" .. which is about $20. In terms of value, it's worth it, as is the Professional .. right now I do not like the misuse of the word free.
MyBase is pricey, the look is impressive, I am very tempted to give it a whiz. Any real downside other than $ ? Does it have real hefty-pizazz ?
Other contenders, most sans tabs, are TreePad, MyInfo, Whizfolders, AllMyNotes Organizer. I think these are some of the leaders in the more traditional look-and-feel. Each has some special pizazz.
Granted InfoQube, Treesheets or another might also be really fine even in traditional mode. If I remember InfoQube was special in your flexible field creation. How important that is for me, as more a database or PIM feature, I am not sure. If I try it, I may like it.
Sticking with the more traditional sense (straight hierarchy) and going around the thread theme, your thoughts ? More exotic stuff is fine, as long as it is strong on the basic "Treepad" (Keynote, TreeDBnote) look as well.
