I use the free Evernote and so this change affects me as well. Although really I suppose it is cheap enough to buy the Plus at $50 per year (don't know what country of currency that's in).
Wow, I don't use it that often but I do find it very handy when I do, so I hadn't realised that I can only upload 60MB per month - good grief that's low!!
Anyway, here's a link to the lifehacker article that explains it:

Interestingly, I'm not sure where Evernote actually talks about it:

Edit
Here's the Evernote link re definition of 'devices':
