Bins and Fences. Google them. They can be "game changers" (CHECK THE GAME TAPE(Jay Mohr, anyone?)) for a Windows power user.
There are also virtual desktop managers around for Win7. Probably easier to install than my experience with Compiz on my Ubuntu laptop. OSX is probably easier out of the box.
Bins and Fences are really nothing like Mission Control. What they are is more like the Dock of OSX rather than Mission Control. What Mission Control does is akin to what Window + Tab does, but it doesn't stack all applications, and it shows all applications on the current desktop with a stack of all open windows of each application. Minimized windows are not shown, but that's trivial.
By multitouch, I mean things like pinch the trackpad to zoom the current view, or swipe with three or four fingers to activate Mission Control and explode all current running windows to see. Having to use a mouse along with my laptop is quite... unproductive in some cases. Plus not all applications support the Microsoft Touch Mouse as far as I see, but all applications under OSX support the multitouch trackpad and mouse just fine.
Don't turn UAC off and don't run as Administrator. You will never need AV software again. Personally haven't used any in over a decade. It's a snake oil business based upon fear.
That's impossible, because certain things like web servers and simulators on my computer do require administrator privileges.
Also I can grant administrator privileges to anything under Mac OSX just fine without fear that it's going to bite me back.
If you like the apps, you like the apps. It's impossible to tell someone to use one of the 1000's of freeware Windows email clients out there if they really like Mail/Outlook/Entourage. That said, guess who is the largest 3rd party software developer on the planet for the Mac? They make Outlook.
Is Outlook included with Windows by default? I sure can't find it in Windows 7. It's included with my install of Microsoft Office for sure. On the other hand, Mail comes default with OSX, and does not require me to connect to the internet or go to some website to download it. It just asks me for the type of account, a login, and I'm in. Also "largest" is by financial asset, not by influence. I'm sure Microsoft does make some very good Mac applications (their Office suite is unbeatable in my opinions), but they sure aren't among the most influential Mac developers.
No argument here. iTunes on Windows is an utter disappointment.
Ironically, third-party does make better iTunes alternatives on Windows. They run better than iTunes, but they still require that iTunes be installed. In any case, on Mac, I get the best of both.
System restore points, Volume Shadow Copy and the out of the box System Image tool - this last is trivial to use. Also $29 backup software (Acronis) that can't be beat. But really you should have a backup strategy that includes offsite/cloud backup copies. That way if your shit gets hit by an F5 cyclone you aren't up a creek. An encrypted (free(BitLocker)) 2nd drive is the way to go.
Well, on Lion, there is a restore partition that is installed along with the OS. It provides a graphical partitioning tool (Disk Utility) that can also be used to make a 1-1 copy of the entire drive onto another partition on an external drive, and that 1-1 copy can also be booted right off that external drive.
There is 0 fiddling, and nothing has to be done.
Not to mention the benefits of a journaling file system:
http://en.wikipedia.org/wiki/Journaling_file_system
Win7 has it now, but not out of the box. Daemon Tools for Windows is one of the dozens of software packages (free) that do this and it's super easy. What Win7 does have out of the box is mounting virtual disks (vhd), booting directly into virtual machines not to mention the free WinXP mode.
Free Win XP mode is not available in all versions of Windows 7, or at least I can't find it in Home Premium.
OSX can also mount ISO along with their DMG file format, and they can also burn those images directly to either DVD or USB. And they don't require fiddling with creating virtual drive. Each mounted image gets its own virtual drive automatically.
Flame away if you want but this isn't an evangelism post. I don't work for Microsoft, family has more iDevices than we should and I like Macs. Currently lusting after a 17" MBP...
No. Why would I flame away? Given your response, I think you haven't had a lot of time with OSX, so I took the liberty to provide more information.
Personally, I don't have a preference in general. Both OSX and Windows have their own strengths. The listed reasons are what I specifically prefer OSX for, but otherwise, I use both Windows and OSX equally on my MBP... on a daily basis, and with the same tasks and almost the same applications, too.
