Everyone should buy RightNote if it helps them do what they do! I'm just too old to make the switch.
Does that mean you're still using your own seminal KeyNote, despite your comment that the interface is now dated, and your evident preference for the search behaviour of EverNote or CintaNotes?
Yes, all the time. I have 15 KeyNote files, of which 9 are archives of stuff I'm keeping around but won't ever need to modify, and the other 6 are in constant use. My Dreamhost logins, account numbers, travel plans, critically important bits of information I need to keep in my head at work, favorite quotes, cooking recipes, to-do lists, emergency addresses / numbers, registration keys for apps I've bought, Delphi code snippets, discussions-with-myself about how best to implement features in my apps, any random snippet of text I want to keep, up to and including my very real world domination plans
It's hard to change the habit and hard to move so much data in a way that won't create more mess than I'd be leaving behind.
OTOH, I find that I have almost no use for all the then-unique special features such as virtual nodes, plugins, or all the rubbish on the "resource panel". I even forgot it existed for a while until I accidentally triggered it :-)
Search in KeyNote is weak, but it does let me search all the nodes and notes when I need. I hardly ever need it though. I tend to remember where a particular node is located in the tree, and 90% of the time it is sufficient to locate it instantly.
I use Evernote only for a handful of things that I absolutely want to have on my phone as well. A shopping list, an occasional Google Maps screenshot or address, stuff like that. So I don't ever get to use the search that's actually quite nicely done. Somehow, I am not comfortable in an app where I have nothing but
search to locate data.
Let's say you're going through an archive of web articles: is it "Guantanamo", "Guantánamo" or "Gitmo"? Bin Laden, Binladen, Ben Ladin, Ibn Laden or... Google handles all that in one query and checks for typos too, but desktop apps don't.
Tagging would help, as it gives you one fixed term for all the possible variants, but (a) entering tags is tedious; (b) having to remember what that special tag is is even worse; (c) there's always the nagging thought, „what if there's a very important article I forgot to tag"? At that point you're back to searching.
In KeyNote I rely on grouping related items instead, and as long as the tree size is manageable, finding stuff by browsing is very easy and eliminates all worries about missing something just because it was misspelled or not tagged.
Of course RightNote does the browsing just the same *and* has both tags and a better search, so it's totally cool to drop KeyNote for it :-)
