I would probably tackle it the same way @gazumped. We've probably all got macro utilities which we could employ to convert notes into pdf, but the logistics of it all (preserving tags, locations, handling embedded attachments, encrypted portions) would make it much tougher.
Ideally Evernote will restore these missing features, but given that this v10 looks like a Windows shell over an embedded web UI, I doubt it. The devs likely want that "iframe consistency" across all platforms, so OS-level differences might be off the roadmap. I'd love to be wrong. I love Evernote and I embrace technological change, but this is a change too far.
