It's a fabulous synergy for the buyer when you dig into his company's situation. Yes, it's going to take "a while" to see a positive ROI, but it throws rocket fuel on their credibility within their niche, and should help them seize an even bigger share of business.
(Also, it's a splendid result for the seller - I believe 99% of people reading this thread, mysely included, would have blinked and sold it much cheaper than the price that was ultimately attained)
