To be sure OS X has fewer problems (I say this based on objective evidence, as my own problems can't count for everyone), but I find the mocking tone of the ads to be in bad taste.
For example, I think it's quite reasonable to say that Hermès makes
very nice scarves. Compared to a scarf one could buy from, say, Walmart, the Hermès scarf will be more comfortable, softer, and backed by some very good customer service.
Now, let's say that Hermès creates an ad which boasts, "our scarves are softer and reduce skin irritation, especially when compared to Walmart scarves."
On the surface, this ad is entirely correct. However, let's say that a few weeks after a new scarf comes out (the one that is boasted to be even more comfortable), a small percentage of customers get hives because they are allergic to one of the chemicals used to treat the wool for the scarves.
Hermès, not wanting their customers to be unhappy, gladly helps out however it can. However, in the mean time, it continues to run ads boasting about its superiority over the Walmart scarf.
Now wouldn't this seem hypocritical? Granted the ads would likely be factually correct (one can critique scarves as easily as one can review operating systems), but can't the ads merely point out how nice and good Hermès scarves are without poking fun at Walmart scarves? Does everything need to be boiled down to a competition?
I think Hermès would do just as well to create a positive ad that picks on no one, just like Apple would do well to boast Leopard's features
without picking on Vista/PCs.
The Time Machine ad is an excellent example of how this can be done. Why can't more ads be like that one?
