I suppose. But I work in an office where everyone has a Windows PC using the full Office suite including Outlook. But professional-level staff get issued work iPhones, and when we want to work on documents collaboratively, which is often, we upload them to Google Docs, and people avoid ever shutting down their computers, because it will take 20 minutes to restart. Just seems like Microsoft had had every opportunity to leverage their total dominance of the basic aspects of the modern office computing environment into something else, yet they haven’t done it. They’ve failed on mobile, the cloud, etc.
Pullleeese!!! Import data and create a crosstab spreadsheet on an iPhone? Create a 3 page Word Document on an iPhone?
All you can really do on an iPhone(any phone for that matter) is take a few notes, schedule, read, review, forward and annotate real work that was done on a real computer, probably by someone else.
