Hi,
That's really interesting. The first zoom level, with correct equations. looks pretty okay. I have a 12.1" Tablet PC, so have tried viewing the PDF in full-screen landscape mode and ti comes out around 6" high, so I think I get a feel for the font size.
Is it possible to remove the white margins at all? That would improve it.
Be interested to see how the other two pages come out with embedded images.
I now have to decide between the affordable Sony, bigger iLiad, and largest but probably easiest for reading iRex DR 1000!
Thanks, you're really helping me decide - I think
