Mac OS X can use any Windows fonts.
SImple as that.
Simple, but wrong. There is a Microsoft vector font format that the Mac cannot use. What you should have said is that the Mac can use any Windows TrueType, PostScript Type 1, or OpenType font.

Postscript fonts are are fonts for printers that support them. Adobe owns this format and you can only use them in Mac OS X because Apple licensed it from them.
It is not at all clear what you mean. It is certainly not true that PostScript fonts are exclusively printer fonts or that they are exclusive to MacOS X. PS Type 1 fonts work very well as display fonts with MacOS X, MacOS 9 with Adobe Type Manager, MacOS 8/ATM, System 7/ATM, and System 6/ATM. Although it is true that Adobe owns the PS Type 1 format, I am not so sure about the terms of Apple's license with Adobe. Apple is an Adobe fonts customer, not a developer to PS Type 1 fonts. I would think that Apple's Adobe license would be limited to its PostScript print driver and possibly its font renderer in MacOS X.

TrueType fonts are Apple's preferred font and most of the fonts that ship with OS X are in this format. OS X automatically notices and handles the differences between the Windows and Mac versions of this format along with a few more arcane details (namely .dfont) that don't really matter to the end user. The font prints and displays smoothly with no jagged edges despite the size.
IIRC, PostScript is the preferred font format for MacOS X. NeXTstep and OpenSTEP, the precursers to MacOS X, used PostScript exclusively. MacOS X is more ecumenical, but PostScript is still the format of choice. However,
all--not
most--of the fonts bundled with MacOS X are TrueType. As an Apple-developed format, TrueType frees the company from Adobe license fees.

OpenType was a joint development form Microsoft and Adobe. Its chief benefit is that the fonts are exactly the same on the Mac and Windows. OpenType was developed in order to relieve Microsoft of its dependance on TrueType. In a sense it is a competitor with TrueType.
You are confused. OpenType is a TrueType and PostScript Type 1 in a single package. I am at a loss where you got the notion that its chief benefit is that the fonts are exactly the same on the Mac and Windows. First off, as a joint venture between Microsoft and Adobe, the Mac was not a consideration. Second off, TrueType and Type 1 are also exactly the same on the Mac and Windows. The two OSs access a slightly different set of characters on the same character matrix. I don't see OpenType as a competitor for TrueType at all. As a said before, TrueType is part of OpenType. I see OpenType as a manifestation of Adobe's official surrender in the Font Wars.

Bitmap fonts are the oldest type and not really supported under OS X. You can use them, but it may not work all that well.
I have no idea where you got the idea that bitmap fonts are not supported under MacOS X. They are most certainly supported by my copy of MacOS X 10.3.7. If they were not supported, they would not work at all.
