much loved NC20 is ready for purchase and presumably delivery. Mind you, this isn't just another Atom-based netbook. This 12.1-incher is one of the first to ship Stateside with a Via Nano processor of any type, the 1.3GHz U2250 in this case. You're also looking at Via Chrome9 integrated graphics, 160GB 5400rpm disk, 1GB of DDR2 memory, and 6-cell Li-ion battery. $550 is the pre-tax price for clicking all the way through to purchase where we suspect you'll be treated to a ship date. One thing's for certain; it'll be later than March 6th.
