Here's a quick BasKet review.
The goodReally, really fast.
It has a great tag for 'code'. Unfortunately, no syntax highlighting

.
Animations for notes (useless, but cool)
Shorcuts assignable to notes
Very good tagging.
Three column mode can be really nice to fit a lot on information on the screen. Good also to compare three things feature-wise.
The BadNo proper highlighting when searching either. You will not see the yellow words we are so used to see when searching. The filter will remove notes that do not contain the word you look for, but where in the notes is the word? Mostly every other program will tell you. Not basket.
It won't do OCR and find text in pictures like oneNote
It doesn't keep indentation, nor does it do folding. It's not a very good outliner.
No indexing/database
No table support
No spelling
Basket has no developer anymore
It won't keep formatting when copying and pasting from a browser
No autocomplete (I use intellicomplete). Not BasKet fault; there's no such a thing for Linux. But this is key to my productivity
ConclusionLots of promise here. Best notetaker for linux I have found. Some features outclass OneNote (so fast). Still, moving to it would make my productivity drop. So I won't do it. THere are rumors that oneNote may work under wine.
Also, for basket to really work for me it must be able to import from onenote (or any format onenote can output to).
OneNote really is the killer app in windows right now.
That, and the fact that Opera's scroll on linux is pretty bad, whereas it's the best on windows, prevents me from fully switching (I live in a broswer).
