Atlas Client Framework
Scoble mentions how Java kind of bashes the fact that Microsoft is building WPF to make a big move even more into smart client applications. You kind of get the sense that Scoble's going back and forth on which is better, web applications or smart clients and some people in the comments, give him some crap for it, but the core idea is dead on: Both Web Applications and Smart Clients have their own individual advantages and to say one is better than the other is fine, but irrelivant. Use the right tool for the job.
Also, in the comments of his entry there are some bashes on Atlas, talking about how it's a bunch of AJAX hype. I'd invite those people to actually look at Atlas in depth. Sure, there's all kinds of JSON serialization and all that stuff, but Atlas is really a client framework for web applications and is much, much more than AJAX.
This is the great thing about Microsoft, sure they're making this cool WPF stuff, giving us some extremely great options for smart client applications down the road, but they're also doing things like Atlas to really enhance both developer experience as well as user experience. I, for one, am extremely excited about both.
