I disagree entirely. There are plenty of situations where a laptop or tablet isn’t “just as easy” to carry. I’ve listed several earlier, but the one that comes up frequently for me is being somewhere without my iPad, and suddenly I want/need a bigger screen to do something on. The foldable delivers that. I don't carry my iPad with me everywhere I go, and don't want to. I don't carry my iPad with me. I'm often in situations where carrying a bag at all is less than ideal. I am not going to bring a briefcase into a networking reception. I am not going to pull out my iPad and work in the back of an Uber or Cab. If I'm on a crowded subway I'm not pulling out a laptop.
Even if you're right that the iPad will be a "MUCH better experience" (which I also disagree with, there's no reason a foldable can't be just as good as an iPad for the type of things most people use iPads for), it doesn't matter if I don't have the iPad with me when I need the bigger screen. Carrying an iPad/laptop usually means: (1) more weight, (2) another charger, (3) a bag just to hold it, and (4) yet another device to keep charged.
To give an example where it isn't "just as easy to carry": business travel. I already have to bring a laptop for work (in a past job I often had to travel with TWO work laptops - one from my company and one from my client), so why add another device in my briefcase? My bag is already heavy. Plane seats are small, the physical space is cramped, pulling out a laptop and watching a movie or working from a tray table in economy isn't fun. I mean, I'll do it if I have to, but I'd argue a foldable has the potential to be a way superior experience there. And that's before you get into the fact that getting to your bag may be annoying, the TSA hassle, the additional risk of theft/breakage.
I'll agree if I am sitting at my desk or on the couch, and my options are "using foldable" or "using laptop/iPad", I can't think of a situation where I use the foldable. But I'm often not at my desk or on the couch.
