R3 Tech Abilities?

I know that most people who own the M11x r3 use it primarily for gaming; however I was wondering what cool things some of the other hardware in the system is capable of. I have not received my R3 yet but was very interested in the following and would like to know what cool things are possible with the R3:
-Bluetooth 3 - what's the difference than 2.1 and does stereo BT work out of the box? Does it work well?
-Intel Wifi 6200 card - does widi? really work? Can you stream Hd and games over the card to a receiver connected to the TV? Does it work well?
-FireWire - why is it still in the r3 and what devices work with it? I know my FireWire hd did not ever work with my R1.
-USB 3 - is it fast on the R3 and do only external harddrives take advantage of it?
-3D capabilities - has anyone hooked up their R3 to a 3d TV or monitor and does it actually work in 3d? For instance, if I had the right cable and monitor, could you play Batman AA in 3D using the M11x?

Sorry if all these questions have been asked before, but I thought it would be great to get answers on a single thread.

 

1. Not sure about the difference between the two but I assume bluetooth 3 has a larger range than 2.1
2. The wifi card connects you to the Internet not your tv, only the m14x and up have that ability
3. You can hook up speakers I guess, not too sure never used my FireWire port
4. Yes it's fast, my brothers laptop has USB 3 and it's quite fast, and no it's not just for external HDs either, he copies an iTunes tv show to his iPod likE nothing
5.no idea, iv never owned a 3d anything

 

Wrong. I have an r3 and it has the intel wireless display which can stream to compatible TV's.

and also OP the r3 has a much better webcam than the r1 its way clearer and doesnt lag at all.

 

http://forum.notebookreview.com/alienware-m11x/606025-deevus-quick-guide-buying-your-m11x.html this guide has good information on a couple questions you have.

The USB is very fast it goes at least 5x faster.

The bluetooth works out of the box as long as you have it enabled.

 

Technically you're both right about wireless display.

The m11x r3 (and m14x+) have Wi-Di, which gives you wireless display to a Wi-Di compatible TV. The problem is, good luck finding one there aren't any. Maybe it's something that will come in the future but as for now there are no Wi-Di devices.

The m14x+ has WirelessHD as an option, which some TV's support (and has Wi-Di as well).

So currently you're both right

*EDIT* As I write this I see there is a receiver you can purchase for a TV now, the Netgear Push2TV to make it Wi-Di compatible but I couldn't find any TV's with it built in yet. At least the m11x now has a way of utilizing it (albeit a receiver needs be purchased).

 

Unfortunately the netgear add on is rather choppy/laggy with wireless from what I gather.

 

Thanks for all the info! I think the Widi would be useful if it could stream games wirelessly to my tv using the receiver. Some of the other stuff I asked was just fluff that I think would be cool if it would work (such as playing games in 3d) but I most likely would not be using it for those purposes.
