x-post from tech-talk... only got a handful of views there, but thought it might get more viewings here.
Was given this as a xmas present from my dad and finally got it in the mail last week. If anyone is unfamiliar with the abs system you can go here:

The abs system has been for sale in Euroland for a few years, but due to bureaucracy it hasn't really made it over here. The system claims a 98% survival rate and there is a strong record of success when it comes to actual use from Europe. I believe the only person to die in an avalanche while wearing one was hit by a second slide while extracting himself from the first.
By sourcing disposable cylinders in Canada instead of the refillable ones they use in Europe, they've managed to get the design approved in north america, and it is now approved by homeland security to fly in checked baggage.
I was given the Vario system, which I believe is the second or third generation of the abs system and is new this year. I bought it through a company in Calgary, but Ive seen them online for sale in Golden (BC) and Utah.
The pack consists of a frame with your shoulder and waist belts, the airbags and the nitrogen cylinder. Onto this frame you can zip different packs, abs offers a 15L, 30L and 50L and Millet has two different packs available as well. I purchased the 30L and may pick up the 50L for overnight trips.
When my Dad told me he was getting this for me for xmas, I was kinda ho-hum at first. I never see them around, the reviews up here aren't great, the old pack design was terrible and I'd heard complaints about the weight and the fact that this was poorly distributed in the old pack. Plus the problems with finding new cylinders in N. america compounded my misgivings.
I've now had two days of touring and one day inbounds at whistler with the pack I can say that most of my misgivings were unfounded. My previous pack was the BD covert avalung, and while the abs pack is definetly bulkier and heavier, I find it more comfortable. The covert always seemed to bump into the back of my helmet.
The waist belt on the abs is well designed, lightly padded and comes with a burly metal clip system. There is a dedicated shovel and probe pocket, which isn't quite as slick as the covert, but definetly very functional. The pack is top loading and feels roomier than the covert, even though it's stated to have two litres less space. Because the airbags expand out the side of the pack, attaching skis a-frame style is not possible, however there is a good vertical carry system on the pack which worked well. The pack has pretty good compression straps, but due to the bulk of the airbags it doesn't go super flat for skiing inbounds/slackcountry.
The first day out i did notice the weight, however I was still trying to get the suspension system dialed, was carting around my SLR, and did about 6 hours of skinning for about 5 minutes of worthwhile skiing. Second day touring got a lot more skiing in and didn't notice the pack at all, and today at whistler enjoyed not having the pack digging into the back of my helmet. The compressed pack was slim enough that I didn't feel it was pushing me off the chair.
Overall I think it's a winner, the ability to stay on top during an avalanche is huge advantage when it comes to companion rescue, negating the need to be dug out. Of course you still run the risk of being strained through trees or rocks and the pack hasnt increased my level of risk tolerance, but I'm sure it lets my parents sleep better. With other companies like Millet signing on, there will hopefully be even more selection in terms of packs that attach to the frame, giving you even more choice.
Downsides so far:
-$$$$$
-extra weight - just need to get stronger (the unit and pack weighs 6.6lbs)
-lack of a-frame ski carry
-I think I prefer clam-shell to top loading, but not a deal breaker
I'll try and add some pics later
