If you can stand the annoyance of reading a hardcover book in the train (I always hated it), then do. I've never really cared what others thought of me, so, my answer to your question would be no. Besides, I've seen so many ereaders in the wild, that the question should have been "do you feel funny reading an ebook?"
(I've so far seen a total of 0 ereaders in the wild, in case you were wondering
