The Acer CloudMobile has swapped from Google Android to Alibaba’s Aliyun OS. The dual-core CloudMobile is expected to be released in China tomorrow for ¥2,999 (approximately $474). This makes it the most expensive phone in the country. Acer chose the cloud-based Aliyun OS for Chinese customers because of its ease, especially for first-time smartphone users. Acer plans to explore Aliyun for follow-up devices as well. One more will be released next month and more will arrive in 2013.
