I have a first generation (model year 2012) Nexus 7 tablet. Nowadays I mostly use it to watch movies during my daily commute. About half a year ago I noticed that one side of the headphone output does not work. After a reboot and plugging the headphone in and out several times it started working most of the times. Then stopped working completely.
Some time ago I've purchased a Nexus 7 tablet (the top of the first series: a 16GB model before the 32GB and 3G versions came out).
The main use of the tablet is testing development projects and watching movies on the go by me and playing games by the rest of the family. I love it as it is comfortable in size, easy to use and quick. Although sometimes it's painful to look at the display after the Galaxy S4 (pixels are too large).
