Technology vs Old School

As many of you already know I recently completed my courses for my state exam.  However, after my Real Estate Practice class I am torn between two worlds.  Some Real Estate Professionals consider the "old school"  methods of a sign a lockbox and a contract is the only way to go.  However...  After attending RAINCAMP  and becoming a marketing major I have been truely awakened to the endless capabilities of technology and there is no telling what is still to come....  I personally can not see how a simple For Sale sign can even hold a candle to some of the virtual tours and complete listing advertising.  It is absolutely amazing how far technology has come.  Anyway... what I am trying to achieve with this post is some diverse feedback on both the pros and cons of the "old school" method and the same for the new "jetson's" age we are upon in the RE Industry.  How does it affect REO's??  Would they be a faster process one way or the other.... etc.  I look forward to hearing opinions because from the professionals I have previously discussed this issue, the preferences in the 2 definitely vary to say the least.  My Practice teacher is strictly old school and swears by it... And the man is very very successful.  And anyone who has attended rainCAMP or has removed their heads from the sand knows that we are on the brink of technology.  Opinions....pls.  The more the merrier..
