A few things in my experience:

- coming home to find a small white box waiting for me after tracking it's delivery to my house, and the feeling of being a little boy on Christmas day coming to me so strongly that it was almost real

- standing in front of the unit that evening with my neighbours, in the dark, watching the blue glow of the graphics playing over their faces; the frozen, hypnotised grins on everyone's face

- sitting stalled in a traffic jam in the rain, in the dark, when someone recognised my empeg sticker in the back window and got out of his car, ran over and knocked on the window to have a look at the real thing

- the buzz I get every time someone comes round to see a demo

Wonderful thing!
