Where do you get your books?

I have never read an ebook for long periods of time because like Bo0ddha said it can probably be very uncomfortable over an extended period of time. Its very covenient though i imagine

I use the microsoft e reader on my laptop. I think this works well, however I would like a good portable reader.

i use my Nintendo DS to read my books and comics

works great!

Can you read ebooks on the PSP?
I have a large collection of ebooks - but i rarely read any of them. The most I can handle is a few magazine articles.

I generally read ebooks on my monitor. It's not really that uncomfortable to sit in my nice chair and scroll down occasionally. I don't have to hold a book, I can adjust font sizes etc, but reclining is difficult.

I usually print them...

I frequently visit some bookshops ;)
I just can't read a book from monitor, my eyes get tired quite quickly :-/
