Acer is developing a pair of Intel-based tablets in what could be a wider exit from the entire netbook category, the company's Taiwan sales manager Lu Bing-hsian said on Tuesday. The seven- and 10-inch slates would use quad-core versions of Sandy Bridge-era Core processors but, reportedly, run on Android rather than Windows 7. Rather than serve as complements, they were directly intended to help in "phasing out netbooks," IDG was told.
