I'm using the clear adhesive protector from Bodyguardz.com:

This is basically custom cut pieces of clear adhesive that cover the back and sides of the N810, conforming to the shape of buttons and speakers, etc. It's like a second skin for the N810 and doesn't add any noticeable heft or thickness to the device. Note that it's a little tricky to apply, and you may have airbubbles stuck underneath it for a couple days, but it does turn out pretty well if you're patient. Another word of caution - removing the adhesive also removes some of the silkscreened letters as well, such as the "Nokia" on the front face and the letters on the battery cover as well. It's just a thin layer that's being removed.

For add protection, I'm using the Boxwave Designio leather case made specifically for the N810, which can be found here:

The leather case is similar to other ones I've seen on Ebay, PDAir, and CarryMobile, flipping horizontally to expose the N810 and with clear plastic covering the keyboard, but the Boxwave design utilizes black stitching for a cleaner (in my opinion) look. Also, the external leather is one piece, meaning the top vertical edge of the unit is completely covered when it's closed as opposed to being partially exposed. You do have to remove the unit for access to the external memory card slot as well as the microUSB port but that's a given in most cases. Another note, when the case is snapped close, the added thickness of all the inner pockets of the front flap tends to bear down pretty hard on the front fascia, so I'd stick a microfiber cloth in between there to protect the N810's case and the screen from getting pockmarked by the stitching.

One last item I'd recommend is the ClearTouch Anti-Glare screen protector from Boxwave.com, available through this link:

I've tried the one that comes with the Bodyguardz full body protection kit, the HD screen protectors from Screenguardz.com, and lastly the ClearTouch ones from Boxwave.com. ClearTouch is hands down the best of the three I've tried. It made the screen semi glossy, giving colors a wet, vibrant look, whereas the other screen protectors made the screen kind of dull. No bubbles, easy application, easy removal, washable and reusable, and the perfect size. I'm not exaggerating. The Screenguardz were too short by a couple of mm, whereas my last attempt to apply the ClearTouch has rendered it near impossible to remove because once it's perfectly centered there is no gap between the protector and the bezel! Good thing I like it so much eh?
