Growth in netbooks has fallen by extreme levels in the first few months of the year, IDC has found. Netbook shipments will still have grown 33.6 percent year-over-year to 4.8 million PCs, but the growth is far less than the about 872 percent that was seen a year earlier. The decline is such that IDC now believes that most were attracted to the category solely for the price, which usually falls below $500 and lately has made $300 more common.
