Cost of the Framework 13 upgrade kit in 2031: £499
The point of the upgradability and openness of the design is that you only have to pay that cost once, instead of every time you buy a laptop. How much will it cost to upgrade a MacBook's RAM if you decide you need more after a year or two? £2099?
On the other hand, if something fails out of the warranty, this is where you win with Framework.
They've proven that they'll keep upgradability going over a few generations which means I'll be buying all my updates from them.
Macbook Pro - You pay for a new topcase assembly
Framework Pro - You pay a new keyboard
Framework 13 keyboard is 60 USD. There really isn't that much difference, and you're getting a free, used battery.
