I am not really one to criticize articles on a whim, but I just got through reading an article on Apollo. The article seemed to trying to rate it or compare it against every kind of online technology out there. From the well established and matured AJAX(relatively speaking of course) to the bright eyed new kid on the block WPF/E which is still not even completely out yet.
Now I don’t see my self as a Apollo expert far from it in fact. I have not had more than a dabble with it. With a bit of logic applied though you can easily see that the majority of the tools listed in the article are all quite different. In-fact Ajax can be ran from inside Apollo. If anything Ajax is something that compliments Apollo or is a tool used by Apollo. AS for WPF/E I have only just starting dabbling with it too but it currently just a browser plugin in development. The only similarity I can see between the two is the fact they are cross platform.
What I am trying to say is that just because products work online it does not mean that they are comparable. Especially when one of the products is yet to be completed.
