After seeing Adam Kinney's Snow Covered Textboxes, it has become clear: I need to get my sister developing with Longhorn. My sister is pretty wicked good at Illustration, and is currently working as a graphic designer in Indy. But she grew up with computers, just like me, and has always displayed an uncanny knack for being technically oriented, but never really got into anything because she's more artistically oriented.
But with Longhorn, the opportunities to create some awesome looking apps is certainly there. Part of me is afraid of the monstrosities that developers are going to be putting together, but you take technically oriented graphic designers and I'll bet there will be some awesome looking applications.
