OSX lion
I switched to the Apple Universe I mean the works with the whole family and the cousins and pets included
Boy what a fantastic feeling after years of hellish windows and WIn machines...
I have spent many hours watching Apple WWDC, special events and the various demos and learned a lot with other Mac experts on you tube.
The multi touch gestures and multi tasking desktops with the full page views and Reader, snap back features of Safari and the seamless AirPlay integration with other Apple devices........I cringe when Thinking about the endless man-hours wasted battling the crashes, navigating through Command window displays and gobbly gook of . Dll and registry and start buttons to trouble shoot idiotic error messages..."..."..."..

but not any more.........THANKS STEVE FOR A MAGICAL EXPERIENCE

QUOTE=NorEaster;14897539]kudos ro r0k for a fairly decent post on some differences between Windows and OS X. I switched recently (Nov 2011) and to be honest, there are things in OS X that are great and somethings that drive me crazy (features available in Win7 but missing in OS X).
Here are some of my thoughts:
QuickView
Like a previous poster mentioned, this is possible in Win 7 with Outlook.
Speed and Stability
While Win7 made strides in stability and performance, I do think OS X is more stable. I can run many many applications at once and while sometimes one app may freeze, I find that it doesn't take down the entire OS. In the past 6 months, I've only had OS X hang on me once (to the point where I had to shut the machine down completely via the power button). I can't say the same for my previous Win7 machine.
OS X Dock
I actually loathe the OS X dock (I'm sure I'll get down votes on this) but here are some reasons why:
1) The Dock does not show thumbnails/previews of the windows. For example: If you have 3 different Firefox sessions running (or rather, 3 different FF windows), you can't hover over your Firefox icon in the Dock to see a thumbnail of each window. This makes switching between multiple running sessions of a given app (or across apps) extremely frustrating. I couldn't believe, with all of the claims that OS X is easier-to-use than Windows, that this is not a standard feature in OS X. I had to buy a 3rd party app (Dockview) in order to emulate this in OS X.
2) App icons in the Dock shift in location, depending on the apps that are currently open/running. For example, the following could happen: You could launch Firefox (which could be pinned to the Dock) and then you could launch another app (such as Preview) which may not be pinned to the Dock. When Preview is launched, it will appear in the Dock but all app icons to the left of it will shift farther left. I know this may sound trivial, but this means my Firefox icon is now no longer in the same location as it was prior to the Preview launch. Pinning an app in Win7 would always keep it there and launching new apps meant the new apps would always get added to the right of pinned apps without affecting the pinned apps' locations.
OS X's "Document" paradigm
In Windows, each window is it's own self-contained app. The menus of a given app are accessible in that app's window (Example: The file menu for an app in Windows is always found in the window's title/header bar). In OS X, each window is a "document" for the given app. This means certain menus (like the FIle menu) for an app are always found at the top of the desktop (not at the top of the window). So who cares, you might say? Well, try using this in a multi-monitor setup. Launch Safari for example, move one Safari window to your left monitor and then try to access the File menu. You'll find that you need to move your mouse back to your right monitor (assuming it's the main monitor that you use) to access the File menu. This is really annoying.
Finder
I much prefer the Windows Explorer to OS X's Finder. Win7 had some nice advances to the header of the Explorer. For example, for any path that is displayed in the Explorer header, you can select on any folder and access a drop-down to jump to a different folder. That's really convenient (and not possible in Finder). You also can't copy a path in Finder (I do this often because I'll create a new folder in some location, and then I'll want to copy that new folder's path because I have several other apps open and I want to save their data to the newly created path)
Printers
I have a networked Epson printer at home and various network printers at work. Finding them and setting them up in OS X was a breeze (in fact, there was no setup). Unfortunately, the same couldn't be said for Win7.
If anyone is reading this and feels there are ways to alleviate the issues I mentioned above, feel free to comment. I am by no means an OS X expert (and some of my gripes above could potentially be a result of my "noob"-ness).[/QUOTE]
