Autodesk now offers (browser-based) and AutoCAD Mobile (iOS/Android). While not "portable" in the traditional USB sense, you can access your .dwg files from any computer with an internet connection.
NanoCAD offers a free version with a familiar interface and excellent .dwg compatibility. It is lightweight and can be configured to run from external media with some tweaking (copying the installed folder and running dependency walker). Autocad 2012 Portable 64 Bit
Integration with Autodesk Inventor Fusion allowed for direct 3D modeling and better handling of complex meshes and 3D surfaces. It is lightweight and can be configured to
