Now that we've shipped our first CTP, I can tell you what I've been working on for the last six months. (No points for guessing!) It's been a lot of work but I'm pretty happy with the ctp. It's definitely not perfect, and there's a some important scenarios we don't solve yet -- while it might be technically possible to write a large data entry forms application on WPF/E, I wouldn't want to be the one to do it, not until we have more controls. But it is a snappy little platform, and I'm constantly amazed how far I can get using just WPF/E and a little JavaScript.

As always, I'd love your feedback. I'm especially interested in feedback on controls and other UI framework functionality -- I'd love to know what kind of apps you'd like to build, what technologies you want to build them with (which controls, what programming languages, what server infrastructure, ...), and what browsers/os'es you'd like to run them on. I'd also love feedback on the input/mouse/keyboard APIs (and yes, we don't have keyboard events yet, we're working on it) -- I've worked on input long enough to have a pretty good idea of what people need, but no matter how much you know there's always a customer requirement you haven't heard yet. So don't hesitate to post a comment or send mail (nkramer at Microsoft), I look forward to hearing from you!
