At the moment, there are two very similar-looking e-readers with black-and-white Pearl E Ink touchscreens on the market, and now, the smaller and less expensive of the pair is up for grabs. The Kobo eReader Touch Edition went on sale today in the US and Canada for $129.99 (or $139.99 Canadian) at Best Buy, Borders, Walmart, and the Canadian bookseller Indigo. If you’ll recall, the 6-inch Kobo is thinner, lighter, and more compact than the Nook Touch, even though its screen is the same size. It also undercuts it by $10 but it lacks the convenience of any physical buttons. Could these trade-offs be worth the trimmer design? We’ll leave that to you and your wallet (and the guy who may or may not receive this as a last-minute Father’s Day gift).
