I use both platforms on a daily basis. There are some business applications in the Windows for which there is no Mac equivalent. For me, using Windows is just frustrating. It's not one especific thing that bugs me its a lot of little things. Like the reminder balloon that says I need to reboot following a security update. *Click* Thanks, but not now I have work to do, 10 minutes later same balloon. Same response. This goes on for hours, and if you forget to click it, the computer just shuts down and reboots. SMS (Screw My System) Hey corporate, thanks for the patch now this mission critical app doesn't work thanks. Identical machines, identical software with identical patch levels and it doesn't work on one of them. Another weekend at work talking to a Microsoft drone who also can't figure out why it doesn't work.
How many times have you reinstalled the entire Windows system because it has gotten unstable. It's amazing to me how many people think that that is just normal. During that rebuild it takes how many patches, reboots, reinstalls and how many hours have you sacrificed to keep that thing running. You probably call it tweaking or tuning.
The last major install I did on my Mac mini I went from Panther to Tiger. A major OS upgrade. Total time ~1hr with 1 reboot all program settings and everything was there and worked. Once I answered the initial prompts, I just walked away. No prompting an hour into it, reboot so it could start the real install, none of that nonsense.
This last weekend I had to disconnect all of the computers so carpet could be installed. When it came to hooking it all back up. Power cables, printer cables, speakers, monitor, mouse, keyboard, ethernet, wireless print server and Treo dock. The iMac I literally sat it on the desk and plugged in. The keyboard, and mouse are wireless the Treo uses bluetooth.
No one can convince you of anything. Buy yourself a mini and use some of those spare PC parts you got hanging around. Test it out for awhile. I did and I'm hooked. I own two Macs now and I'm getting ready to purchase a third.
"In what practical ways is OS X better than Windows?" For me its time and convenience. I spend all week coding on PC's and back office systems. That is one nightmare I don't want to bring in my house. If Intuit's QUICKEN were on par with the Windows version then all of the PC's in my house would have been out of here ages ago.
