Hi, Sorry if this has been posted before my boss was talking about using iPads for work. he thinks we can use them to show clients new proposals. His plan is to use iPads to show clients powerpoint/keynote presentations and PDF's of ads and stuff. My thing is, that if we are using the WiFi only model, and are not connected to the internet. How do i store those Keynote, PDF and .doc files to show clients? suggestions? thanks!
