Sort of thread=jack about Mac. The browser experience differences are
minimal at best across Windows Linux and Mac provided you're using
firefox. Safari still does a better job of sites than older versions
of IE, but newer versions of IE are getting better. I use safari
primarily because FF on Mac feels slower, and I've had problems with
Flash and QuickTime plugins off and on. Then htere's the stupid SSL
security "policies" they've implemented recently.
One problem I've consistently seen on Mac AND Linux is unavailability
of fonts affecting (seriously affecting) the readability of a site.
Using MS Specific fonts (Like say Comic Sans MS which seems so damn
popular still) means the site sin't going to look right on OS/X or
Linux (unless the user has taken steps to install the fonts)
As for Newer macs, they are intel based, and have soem of the same
hardware but they're NOT a PC. Windows runs on them with some help
froma PC BIOS emulation layer, you all know this as Boot Camp. It
helps XP and Vista get booted up on the EFI firmware that Intel Mac's
use. EFI is sort of like an advanced (but non compatible) PC BIOS.
BIOS grew...organically. It doesn't have any real standardization.
That is the reason for EFI. Whether-or-not EFI is superior well...I
don't feel like it is. It's just about as difficult to work with from
an OS developers standpoint as BIOS, but atleast the documentation is
a bit more reliable. PowerPC Mac's used OpenFirmware which is VERY
common in PPC and RISC systems in general (Sun's still use this on
their SPARC platforms). When they made the move to Intel they
realized BIOS was dead and EFI was a good direction to go, so they
did. They had no need nor reason to maintain compatibility with BIOS
and it was a good idea for them to in fact NOT do such a thing.
