Is this the answer? Never bought one before because a) the screens are too small and b) they’re underpowered but I was getting so fed up of lugging around a big laptop that I took the plunge and now think I should have done it years ago!
13″ MacBook Air with a 500GB SSD, 8GB ram and an i7 processor, screen res the same as my 15″ MacBook Pro and less than half the weight. Looks lovely too! I think the SSD makes a massive difference to performance. Shooting tethered in a studio tomorrow so that’ll be the baptism of fire – can it cope?
