Ultrabooks: Your opinion?

Hi Everyone,

Big question really, but whats your favorite and least favorite things about Intel's Ultrabook category of devices in general? I am asking this for some university work so would be really grateful for your opinions! Has this definition helped laptop makers catch up with Apple in terms of design, usability, innovation and customer service or has it hindered the laptop industry in general?

What are your favorite devices where the category has flourished and what are some failure devices that are a bad representation of the Ultrabook brand?

What would you change or improve about Ultrabooks, or are you a happy owner of one?

Thanks very much for your thoughts!
