No worries Rikki - I have since tried a couple of different settings and on colour (not B+W) like this example, it is a LOT better!!!
But the file size on medium is only about 750k for the colour setting...apparently Adobe Pro can optimise even further so one could them down to about 80k with the same quality...
I was about to drop about $400 on a dedicated flatbed scanner, but this is SO quick and easy to use...Can use it anywhere I can take my iPad (or iPhone)...
Means I can scan while watching tele, or wherever.....
It also has a "three picture mode" where you take three pics and it has some algorithms that morph the best bits of all three to get an even better result..
I am not sure if it can save to a multiple page pdf as I haven't gone that far, but Irfan view is a snap to use to join individual pages to a single multi-page pdf anyway
