I am not due to CPAP upgrade until Feb 2012, I will be getting the Resmed for sure.
I lucked out. I am on my thrid CPAP since 2008. I had a sleep study about a year after I started the therapy. My pressure had changed enough that I needed a new CPAP, actually a VPAP. The unit I have now was recently released than but my Home equipment provider did not dispense that one. A few months ago, my VPAP started acting up. IN the mean time the provider had started stocking the S9 series VPAP.
The S9 has many cool features. The hose has sensors that sense ambient temperature and humidity and heat the hose accordingly to prevent rain out.
The data card it uses is the regular SD card where as the S8 used proprietary interface.
