Even if you forget the ubiquity of it... it saves ridiculous amounts of money. 15 years ago, we'd spend like $50k to wire up new office space for 100-150 people. Now... maybe $5k with cable pull.
Yeah, it's ubiquitous but I'm not so hot on the reliability. It may save a lot of money to not wire up an office, but I wonder what the production losses are due to less reliability.
