Sixty percent of the people who bought a netbook thought it was just a cute little notebook, which is why 42% of them were disappointed with the widget's performance according research done by the NPD Group.

The researcher found only 58% of the people who bought a netbook instead of a notebook were very satisfied with their purchase, compared to 70% of the folks who planned on buying a netbook from the start.

Among the key 18- to 24-year-old netbook demographic, 65% said they bought their netbooks expecting better performance, and only 27% said their netbooks performed better than expected.

Amusingly, although 60% said mobility was a main factor in buying the thing, once they got the widget home, 60% of buyers never took it out of the house.

According to NPD VP Stephen Baker, "We need to make sure consumers are buying a PC intended for what they plan to do with it. There is a serious risk of cannibalization in the notebook market that could cause a real threat to netbooks' success. Retailers and manufacturers can't put too much emphasis on PC-like capabilities and general features that could convince consumers that a netbook is a replacement for a notebook."
