I am ready to buy an iPad. One way I am helping to convince myself to get it, is so I can incorporate it into work. My home life is Macbook, Nano and iPhone 4. My work life is PC (bleck). I am a teacher. Can I do Powerpoint presentations, put these on the iPad and hook it up to a flat screen TV and use the TV as a screen to show the presentations? DOes the Powerpoint have to run through Keynote? (Guessing I would buy Keynote App to use?). Do I need to have Keynote on my Macbook? Is there anyway that Outlook calendar can "communicate" with the iPad? Meaning can I get information from Outlook calender to the iPad and vice versa? I can remotely access my email on my Macbook using Citrix applications. Can I do this using the iPad also? My place of work has wi-fi available if that makes a difference. Overall I am wondering if I need to purchase MobileMe and/or iLife.
