I often take my iBook and Fujitsu along with me in addition to my work Dell notebook PC. My company's IT has a tight control on what model of PC employees can purchase (only Dell and a few model options only). I use my Mac (iBook on the road, PBs at home) for presentation, proposal, and marketing materials and export them to my Dell PC. In the recent big company meeting (2 days in the different venues), I used Keynote 3 to do my presentation, while the rest of the presenters are using corporate standard PowerPoint (I also use Office 2004, by the way) on Windows PCs. I think my presentation went smoothly and was done to the key points (I watch the grand master of presenter Steve Jobs when he does his key notes presentations at the major Apple events). Interestingly, several presenters' PCs stalled at the beginning. Also, my colleague PC locked up (something about the network thing; for some reasons, he was not even able to boot up without getting into network) and I had to use my Mac to run a PowerPoint presentation (that was a joint presentation by my office and myself) For my own turn, I hook up my Mac with VGA interface and get going in no time without missing a tempo. After that, one of my colleagues was talking about the current Mac commercials. VP and Director were present in the meeting; so, there is always a hope that the company might bend its rule on "Windose exclusivity" policy.
