What if I just want my top 10 favorites? In Windows I just drag the icon (of whatever I want) to the Start button, then drop it into the list of my favorites (I'm not sure of the actual term for this). Can this be done on a Mac?
Since I open the same 10 or 12 programs or folders or files many times throughout the day, every day, this is pretty important to me. It would absolutely mess up my work flow to lose this feature.
If this already got covered, I apologize.
Sounds like a job for the Dock. The default mode of the Windows 7 Taskbar is very Dock-like. They both generally seem like a handy place to keep your most commonly used applications.
(I Win 7, you Pin to the Taskbar with the default behavior, which turns the whole Taskbar into a Quicklaunch area. Though it is possible to revert to XP-like behavior with a Quicklaunch and worded application references to the right of the Quicklaunch.)
I don't use the right side of the Dock in anything but "Folder" and "List" view. I still miss how Tiger (OS 10.4.x) treated Aliases (shortcuts) of folders: you could see the actual contents of the folder you aliased. Since Leopard, it just allows you to open the folder in a new Finder window. Poo. I created folders with aliases to all of my applications as I've categorized them for years.
(For the record, aliases and shortcuts are similar, but not the same. Worth googling to confirm the subtle differences.)
Strict keyboard navigation is tougher. If you like it, be sure to turn on Full Keyboard access for All Controls in the Keyboard Shortcuts section of the Keyboard Preference Pane.
I miss the split window of Windows Explorer: Folder List on the left, contents on the right. I use Column View most of the time for Finder Windows (Command-3) and sometimes List View (Command-2) if I'm specifically interested in file/folder details. I don't think there are any third party navigation tools that replicate that, either.
If your're getting a laptop, the trackpad is awesome. Nothing like it in Windows that I'm aware of.
I think Control Panels are easier and more straightforward in OS X, called System Preferences with Preference Panes. I think Control Panels got even more convoluted with Vista/Win7 from XP. That said, the Windows gives much more granularity of control than OS X, but many things can be modified with some third party help (you HAVE to check out Tinker Tool).
Is it worth it? Hard to say. If you spend most of your computing in an office with Windows computers in a Windows domain? I say not worth switching. You *can* do everything, but I find it often a little more time consuming than I find it in Windows.
If most of your computing is for personal use and/or you're not integrating into a Windows domain environment? Then I'd say whatever software you need to run and personal preference can drive the decision.
Good luck!
