Yes, I keep using my N9.
Main reasons why (compared to Jolla):

- Harmattan has more intuitive UI with less clutter.
- N9 has better screen. (LCDs have poor contrast and power efficiency)
- Better camera.

Also I have a soft spot for anything Debian. I use debian on my desktop, laptop and server and having apt-get on my phone brings some consistency as I shuffle between them using SSH.
