I received mine a week or so longer, and it is very strong and robust.
Positives:

• Screen protection and great overall device protection
• Access to all ports (except USB)
• Professional looking
• Less likely to slip out of pocket (although the silicone case wins here)
• Built-in stand
• Very tight construction
• Speakers aren't muffled like silicone case
• Full face and my bright-yellow paint job is visible in all its glory

Negatives:

• Does increase size substantially more than silicone case (no surprise)
• Getting it closed requires a little force for it to click
• The leather "kick-stand" does slip out of the grooves; tapping may knock it back
• Price (not bad really, but the silicone one from eBay is like $8.00 USD)

Overall I'm quite happy with it except for the problems with it falling backwards when you have it propped up and it will slip a detent or two. Not sure how that might be fixed, but in a future version perhaps they could put a metal core that sticks out slightly further to catch the grooves better. I LOVE the builtin stand the n800 has and want something comparable in a case.
