Yes, absolutely worth it. I started about running my own mail server about 20 years ago. Then migrated between several mail providers over the recent years. Using my own domain allowed me to preserve the same mail address. Meanwhile I settled at Proton and are a very happy customer.
Too early. It doesn’t even feel like the current generation has really established. Just got the PS5 Pro, and don’t think it’s such a big improvement over the base model. PS6? - na thanks!
