Problem with basket is that you get all the KDE libraries with it, which is a pain if you don't run KDE. Keepnote is what I settled on, but it needs some Dev help I think. It is one person and has not seen an update in a while. Even so it creates XML notes, allows you to structure them top down and search them, allows inputting images. I also use my version of tiddlywiki (Google fiddlywiki) which I tweaked for note taking but it is limited to wiki markup for input. Onenote is great for note taking but has two problems which led me to stop using it. First already mentioned is no Linux support. Second is that it is a bear to get anything useful out of it into another format to actually do something with your notes, even pushing to other MS products is hard.

As a guitarist who works in windows and linux and once in a while mac, one of the issues that confronts live playing and recording live playing is latency. On a six year old quadcore intel processor I am able to run guitarix, a looper, a drum machine (hydrogen) and a simple recorder through jack with 32 samples latency, while the best I can get from windows and asio is 128 samples. WHile perceptually you cannot discretely hear gaps this this short, it turns up in the expressiveness of the playing. longer yet still audibly discretely imperceptible latencies feel sticky and it is harder to get a groove going. If the poster is recording a guitar through a mic and not multitracking then latency is not really an issue, nor is it an issue if sequencing, but for live guitar playing a real time linux kernel available in the debian repos, and some tweaks to services and nice combined with guitarix and jack and a few other programs readily available in the repos can make a mean low latency single purpose linux box a great tool for tracking electric guitar without an external amp. I still do most of my work in windows, but if I need that particular combination, I can go to my older linux box and get one aspect of the performance that it does really well. Also the LV and ladspa plugins have some really interesting spectral effects and other unusual items that are not found as readily in the VST world.

for the personal wiki thing I use my version of tiddlywiki, fiddlywiki. ssynced with dropbox. downside is no wysiwyg yet but it is html underneath so it is cross platform, easy to get stuff out . tags work great and google desktop ppicks it up so it is searchable, unlike zotero which i also use just not so much for content any more. http://way.net/FiddlyWiki

onenote is great if all you ever need what you write in it for is onenote files. if you need to get it out of onenote you are looking at a badly formatted rtf file...you cant even get it into word neatly...or an even less portable mht file ... or what I did to reclaim my stuff, a half day of learning perl oneliners to convert it all to html. I loved onenote for getting stuff in, especially on the fly ocr, (take that, look inside the book feature), but it is worse than useless for actually writing something.
