I bought the Thrive for myself (not an enterprise) for almost all of the reasons you listed. The only thing you didn't mention was the ability to add an SD card which is able to expand the memory even more than a USB flash drive and it is always there in the inside. The file manager is indeed a valuable "app" and in answer to the above comment - I have had no issues with the glass screen cracking.
I am a very satisfied Thrive customer!
