Should I upgrade?

Do you think an upgrade is worthy?

Yes. The light is incredibly useful.

I'm planning to use it for a lifetime (hopefully).

The battery will die eventually. Maybe if things go really well - it'll last, I don't know - 7 years? Not a lifetime.

The Paperwhite 4 has 8GB. That's something around 7,000 books. The Paperwhite 3 has 4GB. That's something around 3,000 books. How many more do you need to store at a given time...?

which color you guys prefer for the Paperwhite?

Black, slightly. I once had a white one - it just emphasized how gray the screen was. Though if you leave the light on high, the Paperwhite's screens look white anyway. Do the newer ones even come in white, though?

You could wait & see if Amazon has Black Friday / Cyber Monday deals. Or just wait in general - historically the Paperwhite has gone on sale every 3 months or so ($20 off).
