The computer, details of which were not available, was first shown in June at this year's Computex exhibition in Taipei. At the time Acer said it planned to launch the computer in the third quarter but the quarter ended two weeks ago with no sign of the machine.
"Worldwide I expect to see the product launch in Q4," Bob Sen, managing director of Acer Japan, had said.
When the computers were first demonstrated in June they were running Android and Windows but an Acer executive said the company would install Android and another Linux operating system in the computers when they shipped commercially. However, that appears to have changed with the launch date, and at least some versions of the computers will include Windows.
"Acer is not going to launch with a single OS, Android. It will be dual-boot, Android with Windows, " Sen said.
In July, rumours hit the web that Acer had actually dumped the Android-based machine. However, it appears these may not have been true.
The Android operating system is based on Linux and was developed by Google for use in smartphones. Several Android-powered phones are already on the market and developers have been working on a version of the OS for personal computers.
