We are talking about usability for business. When you walk into a conference room equipped with a projector you can usually expect a VGA cable (perhaps an HDMI cable too), which you can plug into your laptop (even a netbook) without any additional adapters. With my MacBook Pro I have to remember to always carry that adapter with me. If I ever forget to take it with me to a presentation, I am in big trouble!
Well, I do it all the time, and I think you are making a bigger deal than it is. It is a small cable I keep in my bag. Its a molehill, not a mountain.
