Insignia still does not plan to support Xbox 360 games until we know more about Microsoft's end-of-life plans for the system.
Thank you for your kind support and patience; we hope the wait is worth it! (6/6)

We are happy to announce that Need for Speed Underground 2, both PAL and NTSC/ASIA releases, will be the first EA-enabled game on Insignia, and also our 200th supported game.
We are not currently able to share an exact release timeframe, but we believe it is close! (4/6)

We've also started research into Xbox 360 and Games for Windows Live support, starting with backwards-compatible Original Xbox titles.
This will allow users to play over 100 Xbox Live-enabled Xbox games (once supported on Insignia), including voice chat, on their Xbox 360. (5/6)

And YES we'll be adding mouse support as soon as we can :)
