I liked my fold 3 but the screen protector was a pain in the ass especially since I live in a rural area. The closest place that could install new ones was 3 hours away. I attempted it twice and they had bubbles both times. A friend just removed her protector and 3 months later she had the black line going down the center of the screen. Foldables just seem a little too fragile to me.
Also was kind of annoying because websites and apps would detect the wider screen and add a column down the side of the screen - featuring ads usually. Kind of a kick in the nuts to spend $1500 for a larger screen just to get more ads.
That said, I kind of miss being able to run split screen with apps. It was handy to keep a messaging app on the right side of the screen while I browsed the web on the other.
You get all of simplelogin with unlimited. There is a way to convert your login so you won't lose your setup. And I BELIEVE that it prorated any unused time you had left on your simplelogin account, so you would get credit for the 3 months you have left when you convert it... But not 100% positive on that, check with support. But I do know when I converted mine a few days before simplelogin was going to expire I was charged for a new month of service with some credit applied. So there is a process.
IMO if you're using proton mail, and simple logon anyway and want a VPN then unlimited is kind of a no brainer. It works pretty great for me.
