It is great to see that you are getting into the Device Pages, and including Data Entry-data dynamically!
The tab boxes look great, and they have potential.
Regarding the WNDR3700 page...
Hardware Higlights, OpenWrt Support and Firmware Downloads work pretty nice!
Links... lacks headers for each device... a Matrix/Table, not showing the entire link, just "link" would have been nice, but perhaps it is too much to ask?
Hardware details... I think the idea with the tabs is that it should all easily be visible on a single screen. My screen is 1366x768... and it does not fit
It seems to be quite the same result for WNDR3800.
I guess the purpose with the tab box is make the page easier to navigate (by not having very much tabular detailed data to scroll by). So each tab should be kept reasonably small, and they should have quite the same size as well, to help readability.
The primary/default tab...
Maybe SoC, WLAN Hardware and Modem are not needed.
Perhaps we should include Current Release instead.
...I dont know... just some gut feeling... we need to have a clear idea of what we want to achieve, so the result is consistant rather than confusing.
It already looks good, and I see plenty of potential (to hide, yet make easily available, information that otherwise takes up too much space and attention at first).
