Acer has come up with its new dual-core Aspire One netbooks that let users run both Windows 7 and Google's Android OSs. Hitting the market with the Aspire One D250 and D260, the company allows users to switch over to Windows 7 in case they really don't like to work on Android. These netbooks also feature Intel's Atom 550 processor, according to a report in DigiTimes. The company also plans to continue this strategy and use the dual-boot feature on all upcoming dual¬core netbooks.
