I'm buying the connection lead I need next week. My question is, is this as straight forward as connecting a laptop? The reason why I ask is that I'm wondering if it's "safe" to go to conferences and do presentations just bringing my iPad. I know I can do any last minute edits on it, but of course I can't plug in a memory stick to transfer my power point to the conference room laptop, which is what I'd normally do. I guess I can go online and send the presentation to myself and open it on the conference laptop - I have 3G but sometimes wireless availability is a bit random where I go so I'm not sure I feel comfortable relying on that. If you were me, would you go with just an iPad? Or is it safer to bring along my MBA, just in case?
