I remember about 10 years back I was in a meeting with a new team on a deal pursuit. Everyone there was looking at printed spreadsheets and printed word documents, and I was sitting there tapping my iPAQ PDA and reading the same documents. When I questioned one of the clauses in the document the presenter, who thought I'd been dicking around playing solitaire, was really surprised when he asked "You're reading the clauses on that thing?" somewhat sarcastically and I read the references back to him verbatim. We worked together quite a bit after that, he was a good guy, but so many were so very old school back then. NOBODY would bring a laptop unless actively presenting.
But I prefer that over meetings today where a bunch of people have laptops and are really only pretending to pay attention to the presenter. There's a time and a place for sure.
And these days where I work, any laptops are fine. We mostly have ~14" sized Windows laptops IIRC. Nobody really cares what they are (brand), we just use them. A few have MacBooks of various flavours but the 15" isn't really that much bigger than the previous 2015 13", which is not huge compared to a typical 14" Windows laptop.
