I use mobipocket (free ebook reader s/w) on my PDA phone. I have over 400 scifi ebooks on my phone in a micoSD flashcard, and it takes less than a gigabyte of storage. You can adjust the font and font size to anything that looks good to you. I get most of my ebooks from www.baen.com and www.fictionwise.com . They each have free ebooks that you can download to see if this format works for you. Almost all ebooks at www.baen.com have sample chapters you can read. It's easy to find a pre-quel or sequel to a book that you really like (if there exists one).
You can buy a kindle ebook reader from Amazon books online. There are many ways to be able to select new scifi books to read without spending time in a bookstore.
