These days you see Toshiba, Samsung, Acer, Lenovo and other OEMs announcing the new netbook generation based on the new Intel Atom N450 (Pineview, 1.66MHz clock) and ARM cores.
So far these are only announcements, the first Intel Pineview netbooks are going to be available end of January 2010.
Spring 2010 will see the first interesting news IMHO: Skylight, the first ARM based netbook from Lenovo (Qualcomm Snapdragon) is going to be shipped and the first Intel Atom N470 netbooks should be available as well.
The Atom N470 got a higher CPU clock: 1.86MHz and is going to provide the first real life performance improvements since the introduction of the Atom N270 (1.6GHz, vs 1.66 of the Atom N280 and N450). I'm really curious to see the first benchmarks...
