Lessons Learned from a Technically Disastrous Keynote

Something similar happened to me during my first conference presentation, granted that being only a workshop i had a much smaller audience. I had my presentation and everything ready to go on my MS Surface, but as soon as i plugged in the vga cable, the Surface crashed. I had my presentation on a USB in my pocket so i could quickly grab the chair's computer and continue, but had i not, it would have been a very awkward few minutes.
