New Mobile DJ System

Some of you perhaps know that I am a mobile DJ.  Have been for over 20 years now.  Look over to the left and see the link to our site.
I loooooove what I do.  I consider myself the best in the business because I have an expansive knowledge of music, know how to mix it for any type crowd and am well-mannered yet exuberant.
I always tell folks that it's really not a job.  Well, except for the roadie work...the load in and load out.  Now that's changing as well.
I have officially retired my CD collection and CD players to my music library.  I would carry about 800 CD's to a gig.  Four crates and a suitcase full of CD's in plastic sleeves.
As with all innovations in the business I wait until the bugs are worked out.  There's nothing worse than technical malfunctions.
Well, the laptop DJ has been tested (by others, thank you) and is now a very reliable alternative to CD's.  More than reliable, it's a gas to play with and a breeze to retrieve any one of the more than 20,000 songs I now bring to a gig. 
Best of all, my roadie load has become lighter.  Of course the crates of CD's are gone.  And, instead of a large (3'x3'x3') road case containing 2 dual CD players and a mixer I simply bring my laptop.                                                                
                                                                      Redundancy is a must though.  You have to have back up in case the laptop goes down.  When it was CD's all you needed was extra CD players.  The CD's weren't going anywhere.  A much different situation with a laptop where your mixer and music is all in one small unit. 
I didn't want to invest in another laptop and was in the market for another iPod to compliment my current 80 gig version.  I picked up a 160 gig iPod and this simple but slick looking iPod mixer from Numark.                                                                                                                                                       I can plug my wireless mic into this mixer along with the laptop.  I can sling both systems over my shoulder in a soft briefcase. 
Plus I now get to load all sorts of eclectic albums on my new iPod for my personal pleasure. 
I'm just so thrilled I had to share.  Now, about those big speakers and heavy amps.  Bose has a solution for that as well but I'm not ready to take that step yet.  It's that redundancy thing.
