Now how does that work out for you, because obviously you do not know Windows very well. For example, there has never been a version of Windows NT that did not support (software) RAIDs out of the box - you claim that Windows does not have support for that, but this feature has been in Windows NT since version 3.1 (which was the very first release of Windows NT).
The same goes for backups -- NTBackup does at least support really backup hardware like tape devices/robots, while Time Machine only supports an external hard disk. And again, Windows NT had a built-in backup software since its very first release.
Basically everything else that you are missing in Windows is either available as Freeware or as Open Source applications. CutePDF, FreePDF anyone?
PDF generation in OS X is okay for simple uses, but for the real thing you will install Adobe Acrobat anyway, just as you will also install Adobe Reader for full PDF reading support. Apple's Preview app is just basic.
I could think of a bazillion things that you also need to install on OS X because it doesn't have that, beginning with Growl (which supports a feature that Windows can do out of the box) and Perian and VLC and Flip4Mac.
No OS is complete out of the box, and both Windows and Mac OS X provide much less functionality out of the box than Ubuntu 10.04, for example. But even in Ubuntu you need to install something like VLC manually to be able to watch all sorts of videos.
I hate to feed the roll but Winni, as always your posts are useless. Windows NT? Really? I wasn't aware that that was the popular choice for OS's in the consumer and business market. Sorry but the REAL stuff out there, XP and Vista and to some degree, 7 do not have built in raid support.
Not to mention that yes, there are freeware versions but my point is it should be included in the OS its 2010.
