gollark: I'm interested, and do have a decent amount of available time.
gollark: I just want rectangles. Mediocre-resolution, flat, no-cutout rectangles! They're cheaper, even, and yet everything has the stupid notchy design now.
gollark: Phones are mostly getting worse for my preferences, even: weird non-rectangle screens, no headphone jacks, bigger harder to hold screens, even less durability and repairability, battery-sucking fancier displays and more RAM, and an Android more Google-dependent and locked down every version.
gollark: Ah.
