I've been using the final version of Windows 7 for a few days now and, as a recently converted Mac user, I must say, it is very good. Some features do in fact make it more useable and enjoyable then OS X.
The taskbar is excellent. Aero peak (I believe it's called), where you can preview and manage open windows on the taskbar, is something OS X dock badly needs. Snap-to-fit is also great. I also really dig the way libraries are handled in Explorer; with all your pictures and videos right there, whereas with OS X if I go to my photo library, it's just icons of iPhoto and Aperture.
Another cool thing that I like to see, though it is totally irrelevant, are the backgrounds that come installed. Some of them are beautiful. The only other time I've used a preinstalled background was with Snow Leopard, and it only has one good background. Strangely, the screensavers are the same as ever.
Anyways, I'm just trying to give an unbiased, normal consumers view. I hated vista, and was loving os x, but now...it's up in the air. I like both Win 7 and OS X. Both have great things about them, but windows 7 blows away OS X in windows management now.
And you don't need to buy a whole bunch of software to use windows, in the way normal users would. You can immediately and easily can download a very out-of-the-way virus program and Windows Live Essentials is easy and simple to download for photos, videos and mail.
But heres the thing that keeps me wanting to use OS X; iLife, iWork and the included apps. And this is the most important thing. While both OSs work great and neither is really much better than the other, it's the apps that you really use and OS X has windows beat badly. iLife makes we WANT to organize and edit photos, Photo Gallery doesn't. iMovie makes me WANT to make little movies, Movie Maker doesn't. Mail is much more simple and easy to use (I'm not comparing Outlook here, cause most people wont use it). Contacts, calendars; all better done. The only thing program I kinda like more on Windows 7 is the zune software as opposed to iTunes and that's just cause it looks cool, it's totally unusable with my iPod, so it's irrelevant.
So that's how I, as a normal, everyday computer user, sees things. I don't do anything professional on my pc, I just use it for my enjoyment and the normal things people use it for; photos, videos, music, internet and email.
Both operating systems are now good. But OS X has better included (or in widows 7's case, free to download) applications.
The big question I am battling with as I get ready to buy a new laptop and have to make the decision of OS X or Windows 7, is the higher price of OS X laptops worth it now that windows is good? I say, yes, it is, because of iLife.
That is what os x has over windows 7 that makes me like macs more. iLife.
