PowerBuilder's DataWindows in .NET

I just received an e-mail from Sybase inviting me to the Beta Program of its DataWindow for .NET, I don't know in the rest of the world, but in Ecuador PowerBuilder created a significant amount of followers in the years of C/S applications, mainly due to the power and flexibility of its DataWindow object. To this days in Ecuador, there is a lot of people using PB (or "Power" as it's usual called down here); when we show them our datagrid they react with diverse degrees and flavors of "but the DataWindow does it (better) already", so it'll be interesting to see how the .NET implementation comes.
