I think this truly has to come down to your specific lines of work. Yes, I use my iPad for consumption: ebooks, magazines, video content, casual browsing. I also use it full time for work; I’m a physician and have been iPad Pro only since the 2018 models came out since my EMR is a mobile-first iPad based app which allows for quick documentation and notetaking as well as billing. Outside of documentation time, I use it for reading medical journals (academic PDFs are ~the size of the 12.9) and medical textbooks while handwriting notes when I need to keep up or brush up on something. I can also use it to watch medical lectures in PIP while documenting.
Now in COVID times, we’re doing some telemedicine at around 8-10 patients in a half day’s virtual clinic; the interface is purely Safari-based, and when I’m ready to document or send prescriptions, I just tab over to their chart (the only downside? I disappear in this moment since iPadOS turns off camera access when the active app is backgrounded except for FaceTime, but this isn’t a big deal to me or my patients since we’ve already had a focused conversation and I can continue to hear them if they need to chime in). Finally, responding to patient messages—>Safari; faxing prior authorizations for insurance coverage for medicatinos—>iPP+Apple Pencil to fill out forms or if filled out on paper, using the iPP to scan the document and then using a physician-focused app with built in digital faxing.
Outside of those uses, I use Lightroom and Darkroom (iOS only in that case) on my iPad to edit photos which always feels tremendously more natural than using a laptop for me (not to mention speedier feeling); iCloud Photos organizes all my pictures seamlessly, and I have every original downloaded to my 1TB IPP (~150GB). The Files app is perfectly adequate for my purposes (the hardest I push it is when I occasionally use Apple’s Privacy site to download backup copies of my iCloud photo library, which comes out to ~7-8 25GB ZIP files which I transfer to an external APFS-formatted SSD).
So, a 3lb laptop-like device when using the magic keyboard which undocks to a 1.4lb casual tablet when my above workflows don’t demand text input. An extremely iOS-friendly (arguably preferred) workflow based on my needs, consistent and reliable 10hr battery life, no overheating or fans whirring, no weird slowdowns or jittering when there’s a sudden background process errant on MacOS...and don’t get me wrong, I grew up on MacOS and used it thoroughly until ~2 years ago, but can someone explain to me exactly how my (non-artist, non-designer) needs are better met by a ”true laptop”?
