I got in on the new Evernote beta today through
giveawayoftheday. I'm excited. The new version has a server back end with a web interface and it auto syncs to all your clients. Very cool. I'm currently testing the new web, windows, and mac clients. (BTW: I bought a mac). So far it is working well. The interface has changed a bit and differs between Windows and Mac. There are some features still missing and others not yet polished, but it is looking good. I imported about 200 notes from my existing database and synced them up. My tag hierarchy didn't come across - it got flattened out, but everything else looks good. The web version even does in image text searching like the client apps do. Cool. I think this hybrid type of desktop / web application is the future. You get the best of both worlds.
I've made it on the beta also and I'm just installing it now. I've only used One Note from Microsoft, so I'm looking forward to trying something new.
