With the introduction of Google's chromebook, a laptop device running their mobile Android operating system and manufactured by Samsung & Acer, we are seeing the possible rise of a third computer choice for architects and designers.
Already there are a number of apps created for mobile devices running Android, but now being extended to laptops and the support of Google's ever-increasing market and open source options, this offers a widening of the potential for AEC fields. Autodesk is aware of the market in Android mobile computing and has produced a number of apps for this emerging market including AutoCAD WS, 360 Mobile and Sketchbook Pro.
