I'll save time with my normal witty comments, in answer to your comments.
1. Yes M$ have fecked up a bit with every Exchange release, but even M$ wasn't foolish enough to release it as a service to paying end users, they left it to us in the 'job' to massage exchange into submission so it was usable, which happens before releasing any service to the end users. Comparing anything to a M$ product isn't going to win any arguments, we all know M$ is pants.
2. We use a Mac OSX for one of our DNS, well, one of our DNS's anyway, you see professionals like to go multi vendor on important stuff. As this is the only DNS platform which hasn't been fixed it is now switched off, leaving our Linux boxes(centos, ubuntu, debian) to answer the 2,000,000+ daily dns queries.
You seem to think this article is just another attack on Apple, well I would like to think ElReg would write up a similar article on any tech organisation who provide a PAID FOR service which appears to have not been fully tested/maintained. Oh, hang on a minute they have, for example:--
Now, I'm going to bed with the safe knowledge that my non-Apple/M$ service platforms are ticking over nicely thank you.
