I tried the Swift FX Nano at the DME's store and really, really liked it. However, when my cpap was turned on, the pressure sort of blew the mask away from face, causing massive leaks. The respiratory therapist did not think it was a good fit for me so she ended up replacing my original mask, a Mirage FX wide, with a Mirage FX small. However, she said she was just going to throw away my old mask and the Nano and offered them to me to take home.
My issue with the Mirage Fx (both sizes) is that I wake up in the morning with a red sore spot on the bridge of my nose. It was still bothering my last night when I was ready for bed so I decided to try out the Nano. I really love that the entire thing is made of soft flexible plastic! I woke up with a small mark on my nose from the Nano, but it was the kind that went away after 15 or 20 minutes. LOVE IT!
The biggest downside of the Nano for me is that the seal is rather tenuous. Anytime I moved, I had to adjust the mask. Normally, I put the Mirage FX on and forget about it. But with the Nano, every time I woke up, rolled over, or adjusted my head on the pillow, I had to adjust the mask and/or the straps.
Like the OP, one thing that appealed to me about this mask is the ability to wear it and my glasses. I've been wearing my glasses with the Mirage by folding one side, sliding it under the rigid plastic piece that connects the mask to the forehead support, then opening the side back up and putting them. I thought the Nano would make glasses wearing a breeze but I found that the bottom of my frames rest against the top part of the mask. Unfortunately, this causes the mask to leak like crazy and it's difficult to keep my eyes open when I've got a high pressure wind directed at a my eyeballs. I'm still trying to dream up a solution for this one. I have a terrible habit of falling asleep with my glasses on but I know that won't be happening anymore (at least as long as I use the Nano).
It's possible that I might get better at keeping the mask after I've worn it for a couple times. It's not hard to adjust it, but when I roll over, I want to go back to sleep, not fiddle with the mask. The way positioning of the head straps was very comfortable but it didn't feel like they kept the mask on very securely. Maybe an extra strap or an adjustment will help. I'll have to fiddle around with things more on the weekend.
Overall, I'm very happy with the Nano, despite the difficulties I had in the DME store. I am hoping that the more I use it, the more I will adjust to it, meaning less need for adjustments. I have no idea how to interpret the leak or mask pressure graphs in sleepyhead, so I'm not sure how the mask did while I was sleeping in terms of leaks. However, my AHI was comparable to what it's been the past few nights so even if it did leak, it was not to a degree that the cpap coudln't compensate for.
I hope you'll post back tomorrow and let us know how you did. If you have any tips or tricks for me, I'd be grateful.

I also started using the feature on S9 autoset that turns on when it senses a breath and shuts off when you take it off. Love this feature.
