I am a Windows user with little Mac experience. Wouldn't an Intel Mac with Windows OS installed be the 'least painful' way for Mac users to move on and be able to run things like Quicken, color management, profiling and printer drivers? I have considered moving to a Mac, but with no problems at all with Microsoft, I think I'll stay with Windows.
Yes, an Intel Mac can run Windows just fine. You have the option of installing Windows on a separate partition and having a dual boot system and/or running Windows in a virtual machine.
As the Mac doesn't come with Windows, you need to purchase a copy of Windows. If you want the virtual machine solution, you also need to purchase the virtual machine software.
If you are running both Mac and Windows, you need to maintain both. You need to keep your Windows OS up to date, and keep your Mac OS up to date. Obviously more work then only maintaining one or the other. A disadvantage of the Mac is that you don't get as many choices for your hardware configuration. Although the Mac hardware is quality stuff, and reasonably priced compared to a similarly configured Dell, you are stuck with three choice of desktop: Mac Mini, iMac, and Mac Pro. If you are only running Windows you have many more hardware options available.
Although I have not tested this, I believe that color management would be problematic printing from the Mac side to a Windows printer driver, or from the Windows side to a Mac printer driver. I would suggest installing a Windows driver for printing from Windows and a Mac driver for printing from the Mac. if you have an older printer, you may have a hard time finding a good Mac printer driver, and may need to print from the Windows side, or invest in third party software.
