I want to buy a tablet almost exclusively for reading papers on it. My reading routine is tight to Zotero for reading, highlighting and syncing with multiple devices. Since spending a huge amount of money buying an iPad or an equivalent is not an option, I am currently considering Kindle Fire tablet.

Here is a reader called ZotEZ^2 on Amazon Store that allegedly supports Zotero. Does anyone use this app on Kindle Fire? I am particularly interested in 1) reading, 2) highlighting and 3) syncing databases across devices such that highlights are visible on all the devices.
