I have used a Nemo Hypno EX airbeam-supported tent for the last six months, and love it. I'm 6'4", so I either sleep diagonally or stake the middle of one door out to create clearance. That's as close to a negative thing as I can say about it. I bought an Ahwahnee after coveting one for decades, spotted the Nemo a week later and ordered it, and have never used the Ahwahnee.

The Hypno EX is 84" x 53" x 36" tall, weighs 4lbs 2oz and stuffs to roughly the size of a volley ball with compression (8" x 9" per company lit). A hand pump comes with it, and a foot pump is available. Either way, you can have it inflated in a minute or so. To break camp, deflate in 5 seconds or so, stuff, and you're done. Fastest tent I ever had, and without poles to contend with, also the smallest bundle for that size tent.

It is single walled, waterproof and breathable, and had no condensation inside on a rainy night at the HU meeting in North Carolina last weekend. You can vent low and high, crawl out through the bottom of the door without unzipping the upper zipper (if you're athletic?), and spend as long as you want extolling its virtues to interested parties. In fact, another rider bought mine last weekend (I had a new one plus a Morpho AR--the next size up--waiting for me at home. Gadgets will be the death of me!).

The Hypno EX is not in the 2007 line-up (they say they intend to lengthen it for 2008, as requested), but would be worth looking for (discount camping gear companies, ebay, etc.). I haven't tried my new Morpho, yet, but expect equal results except that it won't pack quite as small (it's 112" x 64" x 42" tall. For comparison, the Ahwahnee is 90" x 53" x 45" tall and weighs 6lbs 11oz packed vs 5lbs 11oz for the Morpho.).
