Here's where you're experience is limited. Free thinking. The Mac was the FIRST of the two platforms to allow people to freely use two monitors and move windows back and forth between them... and to this very day, most of the creative software has significant limitations in Windows that aren't present in the Mac version for reasons that have everything to do with the way the software was originally programmed.
For instance. Photoshop. Let's go there. In Photoshop on my Mac, here's what I can do, that I can't do in Windows. I can stick one view of a photo or painting in one window (magnified), and create another real-time view of that same photo in another window de-magnified... so that as I work in the magnified view (taking up an entire monitor on fullscreen) I can see the demagnified view (fullscreen) in the next window. This also used to be true for Macromedia Director, but its true for Flash development by extension. Stick you "STAGE full screen on one monitor, and have your "score" in the other monitor. Windows is capable of this, but many software packages were written to use MDI and can't change now with so much built upon that foundation.
Wikipedia says this:
"The disadvantage of MDI usually cited is the lack of information about the currently opened windows: In order to view a list of windows open in MDI applications, the user typically has to select a specific menu ("window list" or something similar), if this option is available at all. With an SDI application, the window manager's task bar or task manager displays the currently opened windows. In recent years, applications have increasingly added "task-bars" and "tabs" to show the currently opened windows in an MDI application, which has made this criticism somewhat obsolete."
Unfortunately, the article writer completely ignores MDI's multiple monitor issues.
Ok, so... Mac's have an advantage most non-technical people tend to describe as "I feel more free with using my windows". Another Mac advantage, is that Apple has done a much better job standardizing its interface across the OS. Windows has been catching up to "Spotlight" in the last few years, but hitting a spacebar from the desktop and using "Quickview" to view any document type (as multiple developers submit readers into Apple's pluggable architecture) has been great. I can't say how many times I use the spacebar to "Quickview" items on my desktop. I've added more extensions to "Quickview" inside Zip files and others too. Also, on my Mac, I can hit a function key and have the selected text spoken to me. I can go to ANY Mac installation and set this feature up in seconds. I can also download an automated task that sends any read text to an iTunes audiobook. Which, is extremely great when I want to listen to something on the go that I have no time to read.
One huge feature present in the Mac OS, is the ability to send anything being printed out as a PDF. Whenever I'm remote, or I don't have a printer, or I'm just sending it to Staples for a blown-up version, I use this feature. Standard, fromany program. The "free" program I used to use on Windows was always a pain in the neck, and didn't work anywhere near as seemlessly as the Mac OS implementation that requires no third-party installation (with nag screens).
One of the things my wife's family can attest to, is that owning a Mac has created an explosion of creativity. Using GarageBand (free on every Mac), my young nephews have produced some extremely impressive music. At one point, one nephew wanted to put his music on YouTube with a slideshow, and I suggested he use iMovie (free on every Mac). I expected him to come back and ask me questions on how to use it, but in no time, he was just giving me the YouTube url to go to... and it looked very impressive. I'm also impressed with many other Leopard additions... for instance, the native "Preview" application has me scratching my head how making multiple-page PDFs could be so easy (and free, just dragging pdf pages into one document and arranging them).
Moreover, iPhoto on the Mac has really pressed me to think about being more creative. I took photos from my wedding, and put text to it (in iPhoto), and with one click, purchased a very inexpensive hard cover book version. I was taking a children's storybook writing course and showed the product to my teacher and he was deeply impressed that something like this could be produced so inexpensively ($25 I think for a 52 page hard cover bound book with full color and high quality print). When I finish my children's book, this will be the way I generate copies to send to publishers. The "Places" and "Faces" additions to iPhoto are simply icing on the cake for this great piece of software.
All the stuff I mentioned above... NATIVE. I don't have to install ANYTHING. The fact that Apple's MS Office equivalent is only $79 doesn't hurt either. If you're telling me Windows does all that out of the box. Great. But I think we all know it doesn't. You could go on and on with what Apple has done to help people using its OS, but I think that gives you a general idea.
I'm always looking to check out the state-of-the-art with Windows, but I started Mac, and then realized it was painfully out of day, back when it was OS 9. I jumped ship. I went from being a Windows 2000 fan, to a Windows XP guy... but like I do with Windows now... I kept an eye on the Mac. Once Apple had "fixed" things, and gotten their act together, I came back and got a lot of benefit. At my job, my boss was a PC guy. After a few years as a Windows shop, I convinced him to switch us all over to iMacs running VMware. He's said its been the single greatest decision he's ever made. Our productivity has shot WAY up. Security updates are quick and painless, networking is fairly seemless, and we're continually finding better ways to work. On the flip-side, we deal with lots of clients have are constantly in worlds of hurt on the PC platform. A lot of people make excuses for Windows when they should just keep an open mind about what constitutes "better". With Windows 7 (if you move the whole office over), maybe Microsoft has solved its problems. I can't say yet.
