Thanks! I hadn't considered room lighting - though I also need it bright enough for pen and paper. Resolution seems ok - I zoom in when needed, which is rare.

Thanks! I hadn't considered room lighting - though I also need it bright enough for pen and paper. Resolution seems ok - I zoom in when needed, which is rare. Some pdf's have lines too long to fit on the screen, for the text to be large enough - but they are also rare. I think a 10" would solve that (held lanscape, 10" is basically A4 portrait width, if you zoom out the margins). So it doesn't feel like resolution is a problem - although some people say fuzzier text tires eyes.
