I sorry to hear about you having cancer. Wishing you all the best for a full recovery.
I’m a programmer, so use a work provided Windows based laptop for my day job, but when it comes to work meetings, I prefer my iPad. I’m on medical leave and return to work in just over 2 weeks time and then will need to make a decision regarding using my iPad for work meetings though since my workplace has now introduced a profile that needs to be installed in order to access work email, calendar and work accounts for Skype and other Microsoft products. The profile enforces regular password changes, auto-lock settings, etc, and may prevent access to apps that have been determined to be ‘unsafe’. I’m hesitant since it’s my personally owned device and I want to set it up how I want to. Yet if I don’t install the profile, I can’t use my iPad for work purposes anymore. I’ll also lose access to work provided Office 365.
As for my personal use, my iPad Pro is my go to device now for most things. My iMac is used pretty much to support my iPad and iPhone. I use it mostly to backup my devices and to load videos onto my iPad. I usually take my iPad everywhere with me, but sometimes just my iPhone. I was taking my iPad Pro 10.5 everywhere and mostly left my iPad Pro 12.9 (2nd gen) at home, but now I have upgraded my 12.9 to the 3rd gen it’s even more portable and I’m yet to determine if I’ll be taking my 12.9 or 10.5 out with me now. I’ve only had it for a few weeks and have been off work for medical reasons. I’ll definitely take one of them with me, but which one might depend on whether I decide to use the work profile on my device (I’d use the 12.9 for meetings then) or not (then I may just take my 10.5 for my lunch time break).
