I have a RESMED Autoset 10 (black version though *my* pronoun is 'her')

It's time to get a new machine and I anticipate problems with my insurance as I've had nothing but problems with them since beginning CPAP.
I think I'd just like the same machine I have. I am comfortable with it.
I see that there is a new "Card to CLoud" version. What does this mean? It appears the exact Autoset I have is unavailable many places. I do not want "a brick" or "a trick" and I want to be prepared to advocate for myself if someone tries to force a different machine on me.
I would also like to know if anyone has had problems with the 11? Or if there is a genuine health reason to prefer the 11? The style and look of the machine means nothing to me.
I do not use the humidifier if that makes any difference. I have removed it and the end is capped so that's not a feature that has value to me.
Thanks for any and all advice.
