One of the things I like about Evernote is that its "notebooks" databases are just sqlite DB files. You can take them apart with a variety of tools, and they are easy to back up and move around.

What I don't like about QuickBooks (which I've also got) is that its data bases are rather opaque. You can copy them and back them up but the format changes more often than I like and I don't have any third party tools that can open them. That said, lots of businesses trust their business to Quickbooks (I mostly use it to track expenses so they are easy to import into TurboTax)

What is it about Evernote that makes it a problem in your mind? (other than perhaps it doesn't really have any sort of ledger function like Quickbooks does)
