Right?
Something this old is going to be power inefficient compared to newer stuff, and simply not perform as well.
I would know, I just booted up a 10 year old consumer router last night, because the current one died. It’ll be OK for a few days until I can get a replacement. Boy, is this thing slow.
This is a major reason I root, so backup apps like NeoBackup actually work.
Then Syncthing keeps those backups in sync with a home machine.
Lose my phone? No big deal, setup Syncthing on new one, let files sync, launch Neo, restore.
