Nexus 7 device and app recommendations

Among the 7-inch tablets, from the current situation, only Nexus 7 has a prominent advantage among the general public. I have bought one, and here are the recommended devices and applications.
1. Equipment
Nexus 7 does not support 3G, so it is more convenient to get a wireless router. The blogger bought a Unisplendour U3A and directly inserted the card (it can support 3 networks, no network card is needed).
2. Application
Web browsing related: The built-in Chrome is very useful, and third-party ones are not needed; GAE is convenient for circumventing the firewall
Books and reading related: Kaijuanyi , I have been using it all the time, TXT is the first choice; Xianguo Lianbo HD, read news, blogs, etc.; Google Reader, the first choice for subscribing to RSS, GReader is also good, supports synchronization
Casual games related: Fruit cutting, classic game
Navigation: N7 has a small space, so online navigation is good, such as Baidu Maps and Google Maps.
Electronic market: Google Play, Cool Market (there are many cracked apps)
Input method: Google input method, Baidu input method
