I found a video clip on the msnbc.msn.com website that showed an excerpt from a recent Today Show episode.  Al Roker was discussing with his guest how technology is advancing – moving away from moving parts and towards solid state technology.  This was in reference to devices such as IPODs, digital cameras, and laptop computers.  I found it interesting because I really had not paid much attention to HOW these things were happening.  I have a few of those devices, and just in that couple of minutes I learned a lot about now it was possible for them to be smaller, lighter, and more durable than the older models.  So I feel enlightened now; it seems that solid state technology is ONE of the waves of the future!
