When I tried it might have worked if you'd fully bought into the apple ecosystem, but in a mixed corporate environment it just wouldn't work.

I do a lot of design work in indesign and photoshop, and even word. Being able to make both simple and substantive changes on the fly is a lot more use than far more limited ipad apps.

The SP4 pen is far more pleasant to write with than any ipad stylus I came across. This is all just a matter of taste, but I found my muscle memory reacts for better to the SP4 stylus.

My ipads were great for many things, but work was never one of them for me.
