Apple (and Linux) has a big opportunity to take small business away from Microsoft, though they have been less than deft about exploiting it so far.
I don't have to tell anything to your client, given that I have been using Win 7 since beta for 2 years now, and even in beta, found it one of the best operating systems I have used (and I have used all kinds of operating systems for years, going back to the DEC VAX, and the AS400.
Given that a massive 8 million users downloaded and used Windows 7 in beta, gave great word of mouth from those 8 million beta users, and after that Wiondows 7 proceeded to totally shatter all operating system sales records in history when it was released, I would be calling BS on yet another FUD attempt, by yet another Apple fanboy on yet another internet board. Further, I'll take my own experiences with the product, over those of some anonymous guy that I know nothing about, any day.
Linux was launched even BEFORE Windows NT was launched, and has still not even managed to grab just 2% of the world's desktop market yet.
Apple has been around like forever, and still can't even get 4% of the world's desktop/laptop market. Companies like Lenovo and Acer were founded long after Apple and have managed to sweep past Apple in worldwide market share with ease.

Please pass my contact info to your client. It sounds like maybe a problem with the service provider... ;)
I have worked with Dell, HP, IBM, etc... When you are providing support to people you are providing support. I get issues on Macs, PCs, etc...
The bigger problem is when the business community can buy a PC for $500 or a Mac for $1000, and both can deliver the same results why would you ever pay the additional cost just to buy a Mac?? Until Apple makes inroads with the business world, they aren’t going to get much more traction or market share than they have now.
