I'll probably get this one, ticks all but one of my checkboxes (no SD card slot

):
- Price is competitive (cheaper than the Note Air, more expensive than the lesser P10)
- Kobo & Calibre are old friends, support will probably be excellent
- Kobo's firmware tends to be very solid and long lived in support
If it works as intended I'll keep it., if not, I'll return it within the 30 days window & go for the Onyx.
