Pissed about Vista and MSDN subscription
Me and a friends were talking about how annoyed we are that Vista just hit MSDN, less than a month after our subscriptions expired. I'm sure there are a lot of people like us, who are independent developers that bought in right around the Visual Studio 2005 launch, with the implied promise of Vista in the distance. We were hosed.
I don't think they ever promised Vista would be available, but I certainly remember that it was implied.
Although, if I were really being honest, the next OS I'll pay for is going to be Leopard anyway. :)
