Any updates? I'm concerning to upgrade my account but the premium plan is extremely expensive and IMO not worth it for me as a new user. I'd like to use Evernote on more than 2 devices but I don't need these premium features. My suggestion is medium tier for eq. 5 devices - 1GB and offline editor for mobile devices, the fair price for such a plan is +/- 2$ per month or 20$ a year, II Medium for 5 Devices and 5 GB for 3$ or 30$ and a full premium +/- 4.5$ and 45$.
If you think that it's not enough, You should take into account that OneNote, Apple Notes, Bear(excluding some features) are free.
