In the UK, it's currently an extra £800 to get a 128 GB vs the 64 GB equivalent. So that's more like 3 years of Claude - I think? - assuming current prices stay the same.
Or: you might just feel like £800 isn't an unjustifiable amount of money (one way or another), and tick the box, on the basis that it might just work out. As the saying goes, in for 459,900 pennies, in for £5,399...
I don't think that's true. Plenty of people can run basic workflows at 8GB on the MacBook Neo and most others are fine at 16 GB.
I just hate paying money for cloud subscriptions, and work has given me a decent laptop
