I've been using Evernote since it was a stand-alone app back in 2005. I became a 'pro' customer in 2006. I used to sync Evernote between machines using a flash drive before Evernote.com was rolled out. I've survived many many client and usability and platform changes. I've also lost many posts over the years as they've migrated forum software. I consider Evernote one of my top three paid software services. Can't live without it.
