The value lies in its flexibility. And it's mainly targeted for existing PC players. I can play my whole 150+ games steam library on it. I can easily emulate my favourite childhood games. Also, the smallest version with like a 256 or 512 GB SD card is perfectly fine and a lot cheaper than 600$.
There are use cases where a traditional console is cheaper of course, but you can't get AAA handheld gaming for less money.
Signal needs automatic cloud backups so badly. They're encrypted anyways, why not allow it as an option?
I've used it for years now and it's great and I managed to get all my friends to install it. But manual backups are basically impossible for the average user. Also it'd be nice if we could bulk export pictures more easily.
