[Nexus 7 General] Rapscallion16:
I've noticed the same questions get asked over and over again, so I thought a main post with the answers to the most common questions would be helpful.

1. Should I buy the Nexus 7?

Hell to the yes.

2. Will I still get the $25 credit if I didn't order from the Play Store?

Yes, you will. It is not dependent on what store you ordered it from. The first account that is logged in to the Nexus will be credited the money. I cannot confirm how long this promotion will last, or whether or not it will only be given to people who preordered.

3. When will I receive my Nexus 7?

GameStop has officially released the Nexus 7 to those who preordered with them. Google Play orders also started shipping as of July 13th. Ebuyer shipments have been released as well in the UK.

4. Does the Nexus 7 support MHL?

No, as confirmed by Engadget.

5. Does the Nexus 7 support USB-OTG?

Yes, but unfortunately mounting USB storage natively is not supported. However, it is possible with a root. It does support USB-to-Ethernet and most keyboards/mice will work.

6. Are there any serious problems/defects with the Nexus 7?

Members have confirmed that some Nexus' have a flickering problem, especially when using Chrome, or with a white/gray color on the screen. Also, as confirmed by Android Police, there is a problem with ghosting, or image retention, but some have suggested that this is normal behavior for an IPS display. However, Google and Asus have not been able to recreate these issues independently, which suggests that these issues may only affect pre-production units from Google I/O and review units.

7. Does the Nexus 7's home screen rotate? Does the Nexus 7 have Tablet UI?

No, the home screen on the Nexus 7 does not natively rotate to landscape orientation as on past tablets with Honeycomb and ICS. It uses the more traditional Phone UI, with the pull-down notification tray. However, members have confirmed that with a root it is possible to change the DPI to 170 or 160, which allows the homescreen to rotate into landscape orientation, and also brings on a more Hybrid UI, which allows some elements of the UI run in tablet mode, but not all. (Thanks to nerfman100 for clarification)

8. Does the Nexus 7/Jelly Bean/Chrome support Flash?

Officially, Jelly Bean is not a supported OS by Adobe, and Flash will be taken off of the Play Store on August 15th. This in turn means that the Nexus 7 is not does not officially support Flash. However, many members have confirmed that Flash does work fine when installed on the Nexus 7, but bugs will be expected. Chrome, the default browser, does not support Flash.

9. Can I still cancel my preorder of the Nexus 7?

If you ordered from the Play Store, Google has confirmed that it is too late in the process for most to cancel the order, and will have to reject the package on arrival if they want a refund. It has been suggested that this is only for people who ordered prior to July 1st, but this cannot be confirmed. Most other retailers are allowing cancellations at this point.

10. Are there any good deals on the Nexus 7?

Some online, out of state retailers such as B&H and J&R are selling the Nexus 7 with little to no shipping and no tax. Your order can also be combined with coupons for these companies. If you would like to save on shipping and be able to turn in old games and electronics for credit, ordering from a local GameStop is recommended.

11. Can I buy the 8GB version anywhere other than the Play Store?

No, the 8GB Nexus 7 is a Play Store exclusive.

All of the answers are based on my own research and observations. If there is anything incorrect, missing, or something that should be added, please let me know! :D
