They will be stripped versions, but both will be available. I just mean things like AutoCad 360 and Photoshop Streaming
This works well for standard CAD files

Do you use Autocad? There is an Android version that will work on Chromebooks

If by "portable" you are hoping for an android version, then I recently downloaded the mobile version of AutoDesk AutoCAD 360. I have used it when on the go to do simple things such as annotate, measure, and draft. Is it perfect? No. But it runs pretty flawlessly on my Galaxy Note 5..
I used to use this to look at CAD files since my office uses Autodesk programs.

For CAD I would use Autocad!
