My original argument was that document sizes (pdf, web page layout, 80 char code, et al) generally don't translate well to 7". I am sorry if I was unclear.
But sure, I don't have references so call it an anecdote. :-)
That was why I asked if 'dagw' had good eyesight, or something. Maybe he doesn't want to read a page at a time? Never mind, I'll wait until I meet someone that has those unusual tablets...
I have a 7" Galaxy Tab (1024*600 px, 170 PPI). PDFs are fine, although I like to read them fitted-to-width with tablet horizontal, not fit to page. No problems with web pages using Opera. SSH client fits 85 characters wide by 37 tall (tablet vertical, with onscreen keyboard) at font size I find comfortable. My eyesight is nerd-average, corrected with lenses. Unless you have some studies about this, I'm afraid it's going to be personal experience vs personal experience.
In short, you're using a 7" as I use my 13" laptop. It strains my eyesight to use a 10" as my laptop. I assume this is an age thing; I'm over 40. It influences the eyes badly, sigh.
The nice thing about the 7" is that I can hold it in one hand close to my eyes when sitting back or lying down (it's more comfortable than I can make it sound). It works without my contacts in, which is my yardstick for good enough. I'm sure my eyes don't love me for the close work, but my back wouldn't love awkwardly using a laptop more, so it's all a tradeoff.
