Efficiency with an iPad

I am constantly amazed at how efficient an iPad can be at dealing with certain tasks.


The other day I received an email with an attached document that I needed to sign and send back.
As I was out of the office I was not able to print the document.
What to do? Easy!
I opened the emailed document as a PDF, added a signature using the markup function, and sent the document back.
The whole process of receiving, signing and sending took only a couple of minutes (aside from reading the document).
My iPad is a wifi only model but using Personal Hotspot with my phone I was able to open read sign and send with the iPad.

(I could have achieved the same using only the phone but reading the document was easier on the iPad)
