Need some help and advice/guidance. My son is heading off to college in late August and we need to get him a new laptop computer. I have heard all sorts of rumors of new MacBook Pro’s coming out but he will need it when he leaves for school. Do we go with the lighter M1 MacBook Air or the 13" M1 MBP? Is there a material difference in processing power of those two? Any rumors of when new MBP’s are going to be announced?
