I've read a few posts here and there about people being unable to load certain articles on the Kobo. It seems like Pocket is mostly okay on the Kobo or the feature isn't really widely used.
To test out Pocket's general parsing capability, I've revived my Pocket account and installed the Chrome extension. It seem to work okay, so if you're having problems, maybe an update or reinstall of the extension will help.
I just have to figure out the best way to get Pocket content on to the Kindle (before I decide whether to get a Kobo or stay with Kindles). Pocket doesn't offer that right out of the box, and the third party solutions I've found has a significant interval lag (Send to Kindle takes only few minutes tops).
Thanks for your replies so far. And just in case I've missed it, the Kobo doesn't have a native send to device via email feature does it?
