I just read in the German Chip magazine that HP is coming out with a new Netbook HP Mini 210 (they say in the next days). The 210 CPU is based on the new Pine-Trail technology which gives more performance, integrates a better graphics and consumes only half of the electricity compared to the previous Atom N450. It comes with a 250GB Disk and Windows7 Starter edition.
If you are in the market for a netbook, you may want to wait a few days and check that out. I checked the HP US website and it is not yet listed.
