It's tricky to directly compare Apple's Mac OS X Leopard and Microsoft's Vista, because the two products will be sold to very different markets in different ways. Here's a look at how both differ as products in the marketplace.
The Indirect Choice
Apple is strongest where Microsoft is weakest, and vice versa. Despite the intense interest in pitting Apple against Microsoft, Leopard and Vista simply aren't direct competitors.
Part of the reason for this is that Apple is only making Leopard available for users of its own Mac hardware, while Vista runs on a wider range of PCs than Apple even ships, including of course, all of Apple's Intel Macs.
Door Three?
Similarly, the vast majority of high volume office fleet PCs purchased by the Enterprise won't be deciding between Leopard and Vista, but rather between sticking with Windows XP for the time being or rapidly rolling out support for the new Vista.
The Problem of Macs Running Windows
If Microsoft's decision makers were confident about Windows as a product, they'd be ecstatic to sell additional copies to Mac users. After all, the company makes far more profit selling individual Windows retail boxes at $299 or more than it does on the individual volume OEM licenses that ship with new PCs; OEM licenses can be as little as $25.
The problem for Microsoft is that every PC user who moves to the Mac suddenly has the choice to stop using Windows all together.
The Shoe on the other Foot
That turns the tables on Microsoft, putting the company in the uphill battle position of its 1990's competitors, who struggled to sell their alternative OS to users who already had Windows pre-installed on their PC.
