Talk about Steve Jobs and probably the first image that comes to your mind is him claiming a stage in his trademark black turtleneck and blue jeans, talking about some uber cool stuff from Apple .

Saw this classic video recently (via techcrunch) where Steve Jobs is seen delivering his first big demo- 25 years ago!

Prompted me to quickly put together some more videos. The change in Steve Jobs over the years in some of the more recent videos:

Ipod introduction in 2001

Ipod touch introduction in 2007

The Mac Book AIr introduction

Macworld 2008 Keynote

Cool stuff? If you have some more cool videos to share- just put them in here in the comments. Everyone would love to hear them.
