For those initial free consultations and business meetings, how necessary have you offline veterans found it necessary to buy/have/own/use a laptop? How about a video projector for those Chamber meetings? I'm about to jump into the offline world with both feet but $$ is excruciatingly tight and I need to keep expenses down. That said, I want to be properly prepared. Any thoughts for a seasoned online IMer who's just venturing out into the offline world?
