5-inch screen, and neither Wi-Fi nor wide-area wireless (PC connection required to loadcontent); it might be a different story if larger e-readers with wireless weren’t available for $139 - $149, but I can’t see this being a winner for Sony
And, lo, the era of the sub-$100 e-book reader is finally upon us! Sears (Sears?) has the Sony Reader Pocket Edition PRS-300BC for $99.99 (plus $7 for shipping and sales tax in some states). It's new, not refurbished.
