After initially really disliking Sierra Blue (Baby Blue) I have gradually come around to it. Unlike Pacific Blue, which I instantly liked, this Sierra I am still not 100% sure but I do think that the Apple store renders don't do it justice. Also, not at all keen on any of the other colours and, for me personally, graphite is just too boring and safe.
So, I have now pre-ordered my pre-order for Pro Max 128GB Sierra Blue. For my uses I don't need more than 128GB as have 2TB of cloud storage and shooting in ProRes is not something I would use so not worth the extra expense of getting the 256GB.
