I feel the biggest thing holding the iPad back is software. Not once have I felt my iPad Pro was slow.
What is frustrating are the things you would think would be pretty easy on an iPad, but aren’t. On iOS in Pages and Word, I cannot edit or create document styles. It will accept custom styles in a document I created outside of iOS, however. I had a 12-page paper that I wrote almost entirely on the Mac. I am running the iOS 11 beta 1 on my iPad and I didn’t trust an important production document to a beta. A blog post, sure. Something that is 20% of my grade with a hard due date? Nope. The other reason is Word for iOS has just enough limitations that I didn’t want to run into a wall. I can’t seem to adjust the spacing between paragraphs, for example. I can adjust the overall line spacing, though. I also couldn’t adjust the margins of the document. The professor had stringent formatting requirements and I was unable to make the adjustments on the iPad. I may have been able to use Ulysses to do this. The instructor was firm on .doc formatting, so it was safer to stay native in Word.
Spot on. The limitation as the iPad for your only device isn’t the device itself but the software needed to run on the device. Earlier I outlined some similar issues when it comes to using reference managers on the iPad. I’ve had similar issues with Microsoft Word. At the end of the day, to finish a writing project to run in I had to complete the paper on a Mac.
