This is our chromebook of choice for our teachers in our school district. I really like using this chromebook for quick tasks and the convertible feature of it is outstanding if you need to do any on-screen annotation (like in a screencast, google jamboard, or whatever). We opted for the 11" size for portability for our teachers as well. And now that chromebooks can run google play apps as well it is like having a chromebook and android tablet all in one!
