I have to think though, perhaps the effort would have been better spent creating a port of Blend for the Mac... it seems to me that only a tiny minority of developers would opt for Eclipse over Visual Studio; whereas I'd guess nearly all designers would prefer to work natively within MacOS.

I can kind of understand why they've done it, but I can only hope there's another project underway with that Blend port...

I recently helped a colleague out with an article on Flex vs. Silverlight in the Enterprise.  Both of us have a strong .NET background, and have more recently been heavily involved on a massive enterprise-scale Flex application.  Although I still stand by the original article, I realise it's impossible to accurately and fairly detail each platforms' strengths and weaknesses in one post.

So, I plan to start a bit of a series - comparing different user experiences as created with Silverlight and Flex, and hopefully reaching a conclusion on the benefits of each platform, based upon developer experience/efficiency, and of course how the end result meets the original client requirements.

Each post will focus on a technical area that you may find within any enterprise RIA.  Example areas could be video streaming, datagrid customisation, push messaging, theming/skinning, just to name a few.

It's as much for my own benefit as anyone else's - in order to deliver the best client experience, you HAVE to know what the best tools or platform are for any given situation!
