Guys just FYI this problem is not specific to the N7... LCD screens themselves are polarized either vertically or horizontally, typical polarized sunglasses are vertically polarized which is basically blocking out the the horizontally polarized screen (turned on it's side). The only screens to my knowledge that aren't polarized are AMOLED screens. I have owned several LCD smartphones and they all would be blacked out by polarized sunglasses one way or the other depending on the manufacturer. The xyboard 8.2 has an IPS LCD screen and it's probably just dumb luck if it's polarized in the direction required for landscape viewing with polarized glasses.

For the Nexus7 guys, does it just have one micro USB port? That's obviously needed for charging but has anyone added a hub so that you can charge as well as add more memory? I've got my library on a 64GB USB via the "USB 2" mod but if I add the N7 then it would be nice to have my entire library accessible on screen on the N7.

I came across some very useful information about the polarized sunglasses issue here
Displays can be invisible with Polarized Sunglasses
All LCDs and some OLED displays have issues with polarized sunglasses - that includes not only Smartphones, Tablets, eReaders, Laptops, computer Monitors, and HDTVs, but also the displays appearing on an ever increasing number of everyday products. More and more people have polarized sunglasses and they can significantly interfere with seeing the display - the screen can become invisible and just appears entirely black. Of course all of this should only matter outdoors, although movie stars and an increasing number of regular people also wear sunglasses indoors, so be careful and check before you buy...
Smartphones and Tablets: With polarized sunglasses all iPads go black in Portrait mode. Other LCD displays go black in Landscape mode. Much better is for the manufacturer to set the extinction angle for 45 degrees orientation so that the display looks good in both Portrait and Landscape modes. The Motorola Xoom behaves in this way as do many Smartphones, Laptops and even computer Monitors. Best of all, manufacturers can add compensating film layers to the display that make this effect go away almost entirely by converting to Circular Polarization. The iPhone 4 and Samsung Galaxy Tab 10.1 do that and have no extinction at any angle (just a small color shift - see below). This extinction effect should only apply to LCDs because they use polarized light internally.
LCD HDTVs: Fortunately every HDTV that I have checked has its extinction set for Portrait mode, so the screen will be invisible only if you are watching TV while lying down with polarized sunglasses. If you watch with your head tilted at some intermediate angle then the screen brightness will vary between normal and all black.
3D HDTVs: If you have a 3D capable HDTV and are watching standard 2D content while wearing polarized sunglasses, what you see will depend on the particular 3D technology. FPR 3D TVs (that use Passive Glasses for 3D) are unaffected by the viewing angle in 2D because they use Circular Polarizers - so you can watch in any position including lying down. On the other hand, for LCD 3D TVs that use the battery powered Active Glasses the brightness will vary between normal and all black depending on how you tilt your head. See our 3D TV Technology Shoot-Out.
eReaders are primarily used in their default Portrait mode, so they should be readable and not extinguish in Portrait with polarized sunglasses. But both the Amazon Kindle Fire and Barnes & Noble Nook Tablet are unreadable in Portrait mode with polarized sunglasses. Since both are IPS LCD displays they should switch to Landscape extinction or add a Circular Polarizer (see below). Note that E-Ink ePaper displays found on all of the black and white Kindle and Nook eReaders are not polarized and are readable in direct sunlight with or without polarized sunglasses.
OLEDs should not show any extinction effect because they don't use polarized light like LCDs. The Nokia Lumia 900 behaves in this way, which is very nice, but the Samsung Galaxy S has a surprising extinction at 45 degrees orientation - this effect is due to using an external linear polarizer in a Quarter Wave Plate to reduce the Screen Reflectance.
IPS LCDs can only be set for either Landscape or Portrait extinction. All other LCD technologies can have any extinction angle desired, of which 45 degrees is better for mobile displays. The best solution of all is a compensating film (technically a Quarter Wave Plate) that turns the Linearly Polarized light from the LCD into Circularly Polarized light. That is what the iPhone 4 and Samsung Galaxy Tab 10.1 use to eliminate the effect.
LCDs are everywhere... even my electric toothbrush and shaver have LCD displays.
Digital Cameras: All digital camera LCD displays should have a 45 degree extinction angle so that both Landscape and Portrait photos can be viewed with polarized sunglasses. My Canon S95 and Nikon D90 both fail on this one...
GPS and Automobile displays are always used outdoors and frequently with sunglasses so you would think that all of the manufacturers would have checked to make sure that the screens are visible with polarized sunglasses. All of mine are fine, but several friends and colleagues have reported that their GPS and Automobile displays are invisible with polarized sunglasses.
LCD Watches: My Casio LCD watch is readable with polarized sunglasses. I'm wondering how the new Sony Android Watch and the iPod Nano used as a watch behave with polarized sunglasses.
Unreadable with Polarized Sunglasses: My LCD indoor and outdoor thermometers, Barbecue LCD timer, sprinkler system LCD remote control, (expensive) LCD TV Universal Remote, LCD Pedometer, LCD Caller IDs, and Keurig coffee machine LCD display are all unreadable with polarized sunglasses.
Readable with Polarized Sunglasses: On the other hand, about half of my LCD clocks, my Alarm System LCD, Honeywell LCD Thermostat, and Panasonic cordless phone LCDs are readable with polarized sunglasses.

Ya, that's probably a fair assessment.
For the Nexus7 guys, does it just have one micro USB port? That's obviously needed for charging but has anyone added a hub so that you can charge as well as add more memory? I've got my library on a 64GB USB via the "USB 2" mod but if I add the N7 then it would be nice to have my entire library accessible on screen on the N7.

Just saw it may be working on the 3g

Thanks for the good luck wishes. When I bought this a couple months ago there weren't any out there less than $30. No biggy, I can take less.
