Is the new wave of low-cost ultraportables a threat to netbooks? | Royal Pingdom: "It used to be that you’d pay a significant price premium for a slim ultraportable laptop – machines that were smaller and lighter than typical 5-6lb laptops.

But now that netbooks have carved out a segment of cheap and portable computers in the $200-$500 range, the ultraportables needed to adapt as well."
