Thanks for your replies. Yes, I need a bigger screen. I mainly need the tablet for physics and math college textbooks. Most of them in pdf and djvu format. It does require long reading sessions and my eyesight for reading is not the ideal, so both for comfort and practicality a big screen is welcome, ideally bigger than 15 inches, and the bigger the better.
Would you consider the current Ipad or Samsung 10.1 tablet fit for this? Which tablet would impose less strain to the eye? Or should I wait for incoming larger tablets?
Yes, I've seen the 20in and higher portable screens from Dell, Asus AIO and the like. I also read about
this cool 4K tablet, eventhough its price is outrageous at the moment:
NOTE: I don't have any experience with tablets. I'm used to my current PC's 23in LCD 1600x1200 display.
