What is your setup (hardware, software) and your workflow? If you had to give an elevator pitch - explain why is it the best for you and how it helps you be productive / achieve your goals?
I have a powerpoint and pdf of my deck on a thumb-drive, but I almost never use them (if anything, I'll email them to the person as a followup after we speak). I once met a guy who had a QR-code on his business card which linked directly to a zip file with his business-plan, pitch deck, etc. I thought that was pretty cool.
I own, but don't use a whole lot, a Core Quad Xeon workstation with 16 GB of FD-DIMM and a 2.5 TB AMCC 3ware hardware RAID, as well as a Blue and White G3 Macintosh, and a dual 133 MHz BeBox.
I prefer to use my MacBook Pro as it enables me to work from WiFi spots, for the most part cafes, as well as some all-night restaurants. I am self-employed; being able to work from a cafe enables me to be around other people during my workday, as otherwise consulting can get very lonely.
