Would you suggest 4GB or 8GB RAM for a 4-year student device refresh? I'm looking at the Lenovo 500e Gen 4, and for some reason, Trafera is quoting a much higher warranty price for the 8GB model since apparently, it's more complicated and expensive to repair. Our account manager had to get special approval for it. I remember when people bought 2GB models that crashed on certain websites so I want to make sure we are sufficiently future-proofed for the next 4 years but without overspending. As you know, with Chromebooks, once you pick a configuration, there's no going back.
