Acer is apparently sticking with the same model name as the current Windows XP netbooks when they move to Windows 7.
PCWorld reports that Acer will launch the Acer Aspire One D250 with Windows 7 next week.
The Aspire One D250 Windows 7 netbook has a 10.1-inch screen with 1,280 pixels by 720px resolution, 1.66GHz Intel Atom N280 CPU and a 160GB HDD.
The battery life is only 3.5 hours, but there is supposed a better battery available as an accessory.
Looking at the Acer D250 netbooks offered on Amazon you find the new Acer AOD250-1613 netbook on pre-order that offers the ability to either boot Android or Windows XP Home. I'd rather wait for the Windows 7 version.
