A single business level licence for 3 output platforms is $2697.30, which I think is pretty high. My 2 year Pro MSDN subscription was $3700.
Luckily I won't be paying for the Xamarin if the other guys like it, as it's their business, I'll just use it. The poor bastards recently had to pay ~$1000 for SpreadheetGear and ~$1200 for C1 and ~$500 for Visifire, so it really adds up -- Greg
