Silverlight - ready for business applications?

Since the Silverlight 1.1 was released I and my colleagues started using it in a commercial business applications for some small tasks, where the benefits were obvious. Even the fact the Expression Blend crashes and the lack of controls at that time didn't stop us. We were impressed of the temp of the improvement and we expected to see reliable and ready for business use platform when the final is released. So, now the final is a fact, but is it really ready for real-world business application? Shortly - no. Not yet.
