Hmm...I've seen this, and personaly, I see a few pros and cons.
Pros -
Durable
Huge screen
Touch screen
Thin and light
Cons -
Huge (Not easy to carry)
Expensive (Touch screens are costly)
Possibly low battery life (Batteries take up most of the weight and size of devices)
Wireless may mean Wi-Fi not EVDO or G3 or the like
In conclusion, it looks neat
Too big for my tastes, to be honest, when's the last time you read a book that's 8.5x11 inches? most are much smaller, standard paperback is about 6x4 probaly. But, as they say, competition is always good
Keeps companies on their toes and makes em make new things.
