The Daily Edition remains the only connected reader in the series, a surprising move on Sony's part given its Amazon and Barnes & Noble competition. At the least, I was disappointed that the Touch Edition lacked Wi-Fi and an on-board store; both feel fairly compulsory at this point. My guess is that Sony's emphasis on international sales (new additions to the country lineup include Italy, Spain, Australia, Japan, and China) may have something to do with the lack of Wi-Fi and a built-in store on the Pocket and Touch Editions.
With its latest models, Sony definitely shows its still in the game. While the touch screen technology really does bring the best of both the E-Ink and LCD worlds to an e-reader, the higher price may be a deterrent that holds consumers back. On the other hand, if the idea of touch navigation--swipes to change the page, for example--is a must-have feature, the extra dollars may be worth it.
