"I thought long and hard not about the contents of this article, but about the title. While sure to generate some controversy, this is what I believe to be the case. My personal opinion is that the current implementation of Direct Push overall is better than RIM’s Blackberry device where it comes to push mail access on Microsoft Exchange. In fact, I consider Direct Push to be superior to any of the other offerings on the market when it comes to using Exchange as a backend mail server."
If you are interested in some of the differences between Direct Push and the Blackberry thing, whatever it is called, give this a read. It also talks about costs of implementation etc. I have gone from not caring about Direct Push, to loving it.
