I switched to Niagara a few years ago when Nova was sold. True game changer once you get used to it (which doesn’t take too long). It works great on phone or tablet. And there is still something SO satisfying about watching the alphabet and apps move with your thumb. It’s so smooth and the haptic feedback is perfect (running on Pixel 7, GrapheneOS, and a cheap old Samsung tablet A8).

Mint and US Mobile are both good alternatives to Fi. US Mobile is a bit more flexible since you can use any of the major US carriers.

I have been using the Alpha for almost 6 months. Overall it has been a very positive experience. Even in Alpha, it worked better out of the box on my laptop than Fedora and Bazzite. Especially the printer support and multi-monitor support.
