Welcome Vol, a lot of the guys above have hit on the highlights. I own (well, owned) a Nexus 7 and love it. I returned it when I heard about the 32GB option, and now I'm trying to decide between the Nexus 7 and the Nexus 10. Couple more points that might help your decision:
- Nexus devices that are not tied to a specific carrier (i.e. the Nexus 7) receive updates pretty much right away from Google via an over-the-air update. You've likely heard of the frustration Android users have with updates... that will not apply to this tablet. Device manufactures (Motorola, Samsung, HTC, etc.) put their own UI on top of Android, and it is up to these manufacturers to push out Android updates to their existing phones. Problem is that they must spend a lot of time testing and adapting their UI to work with the new version of Android, and many decide it's not worth it for their old phones, leaving their customers stuck with an outdated OS. This is why I will only buy Nexus from here on out, it's the only way to go if you like being on the bleeding edge. Again... the Nexus 7 will get timely updates for 2-3 years at least.
- I would highly suggest looking into Google Music. It lets you upload 20,000 songs and allows you to view / manipulate / play your library of tunes from any computer, any phone or any tablet via the cloud. You can set it up to upload your iTunes music folder, so it will constantly stay up to date with whatever you have in iTunes. If nothing else, it's a great backup service in case your computer implodes. Anywhere you have a wifi connection, you have your entire music collection (well, up to 20,000 songs). You can easily pin your favorite artists / playlists / etc. for offline mode so that they will be available without an internet connection, which is very useful for flights. Amazing service, definitely check it out. Several of my iOS friends without any Android products use it just to be able to backup their library and play their music from any browser, anywhere.
Nexus 7 is incredible, you won't regret the purchase, especially at the new price point.
