So one cannot save the Pages document as a PDF and then email it, to and from the same

While I do have Pages (older iWork version and a later one in Mav 10.9.5) I seldom use them.
And some older Macs have AppleWorks, a few Office for Mac, etc. TextWrangler, and others.
On the other hand, image format and other kinds of saving methods can be very handy; if not

From Mac OS6.0 to 9.2.2, was a tolerably difficult shift; early OS X to 10.3.9 was an evolution.
Tiger 10.4.11 proved that near perfection was possible in an Apple OS. Then it wasn't until
Snow Leopard 10.6.8 for near perfection to arise again. Yet recent things don't look that good.
