Interesting post on online note-taking apps here.
Looks like Evernote has grown and changed quite a bit -- last time I looked at it, it was Windows-only I think, and basically just a note-taking app that featured (was centered around, if I recall correctly) a timeline view / navigation function. Now, it looks like it comes with some pretty smart OCR/HWR technology, though at first glance (haven't tried it yet) that appears to be server/service centric. Wonder how it compares to OneNote's capabilities in those same departments.
They've also apparently switched from a software licensing model to a software-as-service model.... which I think has it's place, but so does the former, in areas requiring long-term data persistence especially. The other downside I see is the limited web snippet and photo counts (for a serious note-taker), even for their paid version.
