I read text PDF's all the time on my 650.
I read nothing but text PDF's to be honest.
Just throw it in and hit the reflow....
If you are talking about tables, and instances where the reflow doesn't work then NO IPAD WILL WORK ALSO.
I want to meet the person who sat down to read 650 scientific pages on an iPad without a reflow.
These are the books I buy hardcover and enjoy...
