Dealnews has a great deal on the Ectaco Jetbook eBook Reader, an
e-inke-reader (not e-paper) device with 5-inch display, built-in Fodor’s Travel Guide and CIA World Factbook (!!) and an SD card slot for expansion. It supports .txt, .pdf, .fb2, Mobi, PRC, EPUB, RTF files and doesn’t seem to have any built-in storage. It’s available at NewEgg for $169.99 and free shipping, down from $299.99.
I’ve personally never seen this one in action but it looks like it might be a good choice for folks with lots of PDFs hanging around. There’s even a freaky little slider on the bottom for turning the pages.
