Considering buying an iPad?  You may want to wait a bit before you acquire yet another gadget. Software programs like Blio allow users to download books and read them on their device of choice, whether it be an iPhone, laptop, desktop, or electronic reader like Kindle. Blio, a free eReader program that will supposedly be available in February, grants access to more than a million electronic books. Publishers like Blio because it preserves the graphics and layout of the original text. Blio also gives users the ability to highlight and annotate text, hear the text read aloud, and more. It also can support embedded multimedia such as video and audio.
