Maybe it is just me, but I paid only 50€ for late 16 macbook and got late 13 for free.
Ssd and memory upgrades were about 100€ (dumpster ram) and both run ventura and sonoma (OCLP) without a hitch.
And both work perfectly for programming and such.
Is that what they charge? I always wondered why the Apollo guy charged a subscription for premium services, while RiF was like $4.99 one time. Guess that's why.
