I agree with patio11's post... except for his derogatory comments about PAYG pricing.
As someone with a few side projects and start-ups, all of which are at the proof of concept/mildly profitable stage, it matters to me that there's a way to get started for less than $50/month. $50/month * 10 SaaS platforms = my profits.
His approach makes sense if the aim is to extract the most value from businesses; but what about nurturing new companies?
