I've had no troubles with my ebook Readers.
The trouble I HAVE had was with the Sony bookstore, but the Readers I own work beautifully and are a joy (rather than a pain) to use.
My Kindle ebook Reader is especially nice, even though I now must connect it to my computer - which takes all of 2 seconds. Downloading the file takes all of 5 seconds, at the most.
So...sorry you're having trouble with your ebook Reader, but I think experiences vary on these matters, from person to person and from ebook Reader to ebook Reader.
