My answers follow each of your questions.
does a mack need to have out side software to burn DVD's or cd's and
can you
just highlight items and paste the given items into the DVD drive
and poop
they will burn?
Yes, just like Windows. If you want to burn DVD video discs for your
living room DVD player, that's a little trickier. Audio CD's are easy
with iTunes.
is editing as simple as stopping the reader and adding
more text to a given sentence?
Yes.
is there a read all in the active window
command?
Yes. VO-A
and for normal use is there quite a number of hot keys to memorize
to be able to open edit and save, other then using say a tool bar?
Yes, just like Windows, there are shortcut keys for most common
commands. And, unlike WIndows, you can even add hot keys to any menu
commands that don't already have them.
is there
a quick way to read mail, with out doing different command
interactions?
Interactions aren't a bad thing, but the answer is yes anyway.
Pressing VO-J on a message will read it automatically if you have the
preview pane showing, and pressing enter on it will open it and read
it too.
is there a hot key that we can use for spell check in any program?
Yes, Command-Semi-colon works in virtually any program that accepts
text for spell checking.
also what is the learning curve like transferring from a PC?
I recommend reading Memoirs of a Blind Switcher article at www.Lioncourt.com
for a full answer.
