I tweak my gear for what I need. I’d rather have an ebook reader than read on my phone screen, for a variety of reasons. If you want a convergence device, fine, go for it, but I’d prefer having multiple devices that do a job better (and carrying what I’ll need) than using a convergence device (which feels like a jack of all trades but master of none situation).
Granted, I also always travel with a shoulder bag. Whether it has something like important paper materials, a book I’m currently reading, an eBook reader, or something more outlandish, like a knitting project, I find having a bag handy to be very useful. I carry around enough stuff that this modern idea of just carrying a phone seems alien to me. I get minimalism, but there’s a point where minimalism infringes on comfort and even productivity. I need a wallet, including some contents that can’t be digitized yet, keys, a keychain accessory or two that’s part of my EDC kit and that can never go digital, AirPods, pen and paper, phone, and that’s just my pockets. And, if I’m going to carry a bag, well, I might as well use a tablet over a folding phone.
