IT World compares the features of Microsoft's new Windows Vista with Apple's upcoming Mac OS X Leopard:
It seems as though we've been talking about Vista for ages, and although RC1 (Release Candidate One) came out in September, it's likely to be February before most of us see the finished article. However, its features and general look and feel are fairly common knowledge -- and now we have something tangible to compare it to.
Implementation strategies Leopard is an upgrade to Mac OS X, whereas Vista replaces Windows XP almost entirely. Both Apple and Microsoft released OSes in the autumn of 2001 -- Apple's was OS X Puma; Microsoft's was Windows XP. The difference is that XP is still the current version of Windows, while Apple followed up Puma with Jaguar, Panther and Tiger – Apple has a lots-of-incremental-upgrades philosophy, compared with Microsoft's big-upgrade-once-in-a-blue-moon approach. The two major service packs for XP have been relatively feature-light.
