Re: Productivity - I am just at the beginnings of WPF but the first thing that struck me about controls defined in XAML was "My God those are just big 'ol chunks of text that completely define a control and can be inserted anyplace and cut and pasted and stored and snippet/field subsitututed and .... "

I've been writing a lot of Winform components to drop on forms and do magical things and to do them right definitely takes longer that the XAML approach. I just think the whole idea is very cool, especially when I'm sure there are tools (Blend?) that can write some pretty fancy XAML the way Dreamweaver writes pretty fancy HTML which you can eat as served or season to taste and which can then be the subject of the kind of cutting and pasted that allows reuse.

The one question to ask yourself (esp. if you have a vertical market app) - how hard of a time would I have selling my app if I was competing a vendor that had an app that looked like that vs my current app? Regardless of features people have a (positive) gut reaction to attractive UI's.

>>>Did you see the code demo for those at the end of the video. It *doesn't* take a lot of time or effort. The amount of code is minimal. I've got a scrolling listbox built on the same principal. It took an hour or so - but of course you can spend more time playing with gradients etc. if you want to.

>>Well I think that Paul has a point that an application to be sold is going to market better when it has all the visuals but for a system developed for one client it would be a mistake to get too hung up on how it looks. The only benefit would be if you used that application as a selling point to other clients and that might not always happen. I noticed in the video the repetitive thanks to the client.
