It's a toss up between Amazon's Kindle and Barnes & Noble's Nook as to which one wins the popularity contest in the eBook reader market, but according to Sony, its new Reader Wi-Fi (model PRS-T1) trumps them both when it comes to being lightweight.
Sony's Reader Wi-Fi weighs just 168 grams, or less than 6 ounces. That makes it the lightest 6-inch eReader the world has ever seen.

"Slipping effortlessly into a bag or pocket, Reader Wi-Fi is no bigger than a paperback book," Sony said in a statement. "8.9mm thin and weighing just 168 grams it’s supremely comfortable to hold, with a gently curving profile that fits naturally in your hand."
The Reader Wi-Fi also features an enhanced touchscreen, access to the Reader Store, it's the first eReader to allow book lovers to borrow eBooks wirelessly from public libraries via na on-screen Public Library icon, 2GB of storage capacity (enough to hold around 1,200 books, according to Sony), microSD card slot, and one month battery life (3 weeks with wireless on).
Look for the Reader Wi-Fi to ship in October for $149.
Maximum Tech's take: Under 6 ounces is a pretty remarkable achievement. The third generation Kindle, which itself is comfortable to hold, weighs between 8.5 (3G) and 8.7 ounces (Wi-Fi), while the Nook Touch Reader checks in at 7.48 ounces.
