Yes. It has 16GB of memory.
Much like a camera app on an Android phone, the Nexus 7 also has its own camera app. If you have the 2012 Nexus 7, it has one front-facing camera. On the 2013 Nexus 7, you have a front- and rear-facing camera. The app is defaulted to the rear-facing camera, but it can be toggled depending on your needs.
Nexus 7 tablet 2013 Has a front and rear Camera.
In the 2012 Nexus 7, it came with a single camera (in the front). The 2013 Nexus 7 has two cameras, one in the front and one in the back.
Yes. On the first generation Nexus 7 (2012), it has a front-facing camera. On the second generation Nexus 7 (2013), it has both front and rear-facing cameras.
The initial release of the 2012 Nexus 7 did not have the camera app installed, but future OS updates should have installed the app. If one still isn't installed on your Nexus 7, you can download a third party camera app, and it should function the same way as a smartphone camera app. The 2013 Nexus 7 should have the camera app pre-installed.
If you're equating it to content, and this is similar of other devices across platforms, 32 gb can store roughly 7000 songs or over 18,000 pictures (on a 5 megapixel camera).
I was faced with this dilemma myself upon purchasing a Nexus 7 last fall. There is no built-in camera app on the Nexus 7, but there are two options that worked well for me. 1) you could go to Google Play and download the free Camera Launcher for Nexus 7 app from developer MoDaCo. (https://play.google.com/store/apps/details?id=com.modaco.cameralauncher) 2) Download the popular photo sharing app, Instagram, also available from Google Play. (https://play.google.com/store/apps/details?id=com.instagram.android) Don't expect great results when you take photos with the front facing camera on the Nexus 7, as the resolution of the camera is a mere 1.2 megapixels, and it's a little tough to get a good photo of anything using the front-facing camera. Well, unless you're only wanting photos of yourself, then it'll work just fine.
Yes, it does.
It appears you can only delete the auto backup pictures from the desktop version of Google+, while leaving the picture stored in the Nexus 7. If you want to delete the pictures from the Nexus 7 itself, you can do this through the Gallery, Google+ (Photos dropdown), or the Photos app.
Yes, but only on the front, no camera on the back, so you can only take selfies
You are able to purchase the Nexus 7 on online vendor websites, such as Future Shop or Best Buy. As well as this, the official Store offers the Nexus 7 available for purchase.
