This part is irrelevant - you can render any document size on any display, it is 'only' the question of readability. On a 3.5" display you are talking about sub-millimeter sized letters, and if that's acceptable, I'd like to ask for a second opinion from your ophthalmologist Seriously, try it out on a N900 if you can, for example in terminal, you can use *really* small fonts but it's not pleasant at all, especially for prolonged use (like books and publications). And it's not the point of not having enough pixels, stuff simply gets so small you literally have to look at it like a baby, having the device 10cm from your eyes.

But then we're back to the fact the eee 901 has a larger screen...

I'll try it out on an n900 when I can. "When" being the operable word here.

(FWIW, I usually have very small fonts)

Your claim was:

But but but your eee PC has a lower DPI! Last time I looked at that model it was around 150, so that shouldn't be possible.
Assuming that the "that" you're talking about is reading a full column of text, I claim that it *is* possible. You're arguing in circles.

Also, this depends on what the meaning of "is" is. Or, more accurately, what "rendering" means. Yes, you can technically render the entire works of Dickens into 1 pixel, but I'd not really call this "rendering".

Second, upon what do you base your "sub-millimeter sized letters" claim? On my n810, a full column of text (rotate right, and fit to page width) gives a letter size of approximately 3mm high and 2mm wide (eyeball guesstimation; I don't have a ruler handy). n810 has a 4.1" screen, and n900 has a 3.5" screen. .6" is approximately a 15% reduction in diagonal length. At 3x2mm, this is becomes 2.55x1.7mm. I think this would still be legible.

Anyhow, it's clear we have a disagreement here. I go with whatever. It's not like I'm a nokia designer or anything. Nokia has my feedback if they want it. If you want to keep telling me that I don't want what I want, then please keep talking and kudosing yourselves.

Here, for reference, is the same page, rendered using evince (2.28.0 on the eee, 2.21.1 on the n810) at 800x480 (n810) and 1024x600 (eee 901). Screenshots were taken with gimp (eee; compression level 3) and screenshot-tool (n810).

800x480:


1024x600:

The file, it should be mentioned, is ArXiv_0710.0622v1.pdf. You can get it from arxiv.org

Ummm I don't think ANYONE here questions the fact that higher resolution provides more detail and clarity when rendering a document (PDF in your specific case).

The only concern is applying the high resolution display to a such small physical screen area that it's not practical anymore. That the benefit is lost due to other bottlenecks (your frickin eyes) meanwhile it puts unnecessary burden to the system, cost and whatever else.

Please reread all the previous posts with this fact in mind and I think we'll be on the same page.

That might be; that's why we need to quantify, something people have thus far failed to do.

That gate swings both ways, friend.

Here are two snaps. I didn't rotate them as the built-in pdf reader doesn't support rotation(yet), but the width (and thus letter size) is about right. I have no idea how you judged 3mm high characters on a N810. That would mean (huge) 1cm letters on a US letter sized paper.

You can clearly see the letters fitting between the 1mm lines (the sub/superscripts being less than 0.5mm). Reading this is NOT convenient, more resolution would NOT make it better from a practical standpoint (only more tempting to mess up your eyesight). There is only so much your eyes can resolve.
