Most people pay more than $50 (or even $100 or $200) a year for far less useful services than a managed collaboration suite with full support.
To put it in perspective, Netflix costs ~$108 a year. People have no issues spending $4 a day on a latte, but just 13 lattes costs more than a year of Google Apps. A single latte or a big mac meal at mcdonalds costs more than an entire month of google apps for you.
