How convenient are handhelds to read E-books ? Specially in terms of eye strain and power lasting etc., ?
They're not bad as far as eye strain. Better than a CRT monitor, maybe not as good as a laptop LCC. Of course not as good on the eyes as a paper book,
What does that mean, "eye strain"?
As far as I know it's a subjective phrase.
How are CRTs "bad" for the eyes, and print books "good"?
I don't think CRTs are bad for the eyes, and I don't think print books are good for the eyes. Both tire my eyes out eventually, and CRTs do it quicker than (typical print size of) printed media.
What is the medical term for the condition known as "eye strain"?
I don't know if there is one. And because I view it as subjective, I chose to talk about it in relative terms: on a scale of CRT-to-LCD-to-print reading, my Palm device lands somewhere between CRT and LCD reading. On a larger scale, I'd probably put driving a car for long periods of time, reading in low light, and focusing on tiny glasses-screws as causing more eye strain than CRTs, if that helps.
What will happen if you have too much "eye strain"?
I can't speak for anyone else, but when I feel my eyes have been working to hard, I have to blink more often, I have trouble focusing my eyesight, I'd rather stop reading than continue, and I generally would rather have my eyes closed. Sometimes headaches and overall tiredness follows, but tired eyes alone are enough of a pain without other symptoms.
As far as I know, "eye strain" may as well be all old wives tales.
If you're talking about an actual medical condition (where, say, working your eyes too much will lead to damaged eyesight in the long run), then I have no idea whether that's true or not. Sounds like common sense, but I'm no doctor. But my eyes get tired after working too hard. That's what I call eye strain, and that's what I was addressing in the original post. YMMV.
