Ohad explains the reasons he isn't switching to team system.
I'll give you my reason: the price is quite simply obsurd. Maybe Microsoft talked to the Flex team about their genious "price yourself out of everyone's range" licensing scheme. Wouldn't be so bad if MSDN gave you access to team system, but no, MSDN Universal gets you a trial, and even with your MSDN discount, team system is rediculous expensive. Like I am really going to pay $11,000 on top of my MSDN to use Team System. Give me a break.
