I read ebooks every day, and have never even thought of doing this. Smaller tablets are so easy to handle there's just never been a need. I do open and reverse the screen to watch videos, but for e-reading, I just grab it in portrait mode, fully swiveled and just dandle it on my knee.

I scan my books, OCR them (some times difficult cause it contains too many equations) so that I dont have to carry like 3 800 paged books to school. The most difficult thing when reading in a tablet for me is the heat and the fact that i get overly distracted by the internet :p

Why would anyone do this? Just get a book holder and put your tablet in it....

Yeah, I don't get why it's left open, put it on a cheap book stand in portrait mode or (ideally) a docking station.

I do the same as yucao: I am using Endnote to store and organize my library (mostly stuff I need in grad school) and Acrobat Professional to read; the latter does OCR texts and you can use highlighting easily, as well as search; and again, as well as yucao, I am distracted by the Internet;P

I have Tecra M7, which is terribly heavy for this (it works fine with XBrand Laptop holder though), but my recent purchase - Samsung Q1U - is just perfect for this.

I usually either use it in my lap in either landscape or portrait, or set it on a desk (or restaurant table) with the keyboard facing away from me but the screen flipped around to face me, like this:

_\ O


Where the underscore is the keyboard, the backslash is the screen and the Oh is my head.

Amazingly, no one ever seems to give this odd configuration a second look when I'm in a public place.

For 3+ years I used an LS800 as an ebook reader. It is a slate style, not a convertible, but it worked great. I am sorry motion isn't coming out with a refreshed model.

This is totally embarrassing, but before I had a Tablet, I use to have a Dell 700m, just a 12" widescreen laptop. And for a time, I actually turned the computer on it's side ( the base of the laptop would sit against the wall ) so that I would have the screen in portrait rather than landscape because it was just so much easier to read webpages and stuff, course that meant I had to type against the wall... Good times... :-D...

I'm using a Ergotron Arm for this.

I use a TabletKiosk Sahara slate i440D - so no problem w/portrait mode.
Put it in touch (rather than digitizer) mode and ereading is a breeze.
