I also often carry a voice recorder backpacking. For me it's a Olympus V90 which I purchased in the 1990s
I really like it because it's smaller, lighter (31grams), and more ergonomically shaped than current recorders. It also has a replaceable AAA battery. Nowhere near the record time of the modern recorders, but I am typically just doing quick notes to self, so I don't need a lot of time.
My wishlist would be be the same size/shape, less weight, at least IPX7 water resistant, bigger memory, with usb sync which would auto-transcript the notes and give a user interface which lets me listen to the recording while the transcription is highlighted and lets me edit the transcription to clean it up. Bonus point for nice integration with Evernote.
For backpacking, I actually like the object being in my pocket with a start / stop button -and a lock switch, because I don't need or want continuous recording and given weather I want to bring it to my mouth (often with hand cups over to block wind). Mounted on shoulder strap would be too likely to pick up wind be unnecessarily exposed to weather, and doing an in-the-ear approach (which are used by some devices I use) would be bothersome.
When not backpacking I would love something like kapture except I would want it to have a longer memory buffer and not interested in the easy sharing feature but have easy editing (ideally with sync / transcript feature above).
