From the press release:
288 Vroom LLC today is delighted to introduce The Complete Edgar Allan Poe, their slick new eBook reader for iPhone and iPod touch. This amazing collection includes the complete library of Poe’s great tales and poems. While Poe was the master of macabre, many of his works included mysteries, satire, and humor, including a few hoaxes that were printed in newspapers of his day.Beyond the tales and poems, The Complete Edgar Allan Poe also includes his only completed novel, selected essays on writing, Stonehenge, even furniture, and more, plus some of Poe’s unfinished writing. The Complete Edgar Allan Poe contains a total of over 150 original works by Poe.
I would pass, myself. Vroom is selling it for $.99, and I know that I can read most of Poe's work for free on Stanza. Feedbooks has a lot of them, and you can download from inside Stanza.
