Google, Kingsoft and Docs to go. . .oh MY!

What is the difference between these different word processors and how do I decide which ones to use?

- Very full/robust product suite 
- Easy to use

- Hard to upload to turnitin.com (have to save somewhere else first)
- Hard to organize files for long term storage
- Does not keep file formatting when interfacing with MS Word

DOCS TO GO (FREE)

PROS:
- Can create a document in MLA Formatting
- Has been around and free for a long time (many "quirks" have been worked out)

CONS:
- Hard to get used to using, not user friendly at first

The "Mini-USB" ports on the chargers for the tablets are VERY DELICATE.  Please plug and un-plug them with CARE.

Turn off auto-correct that shows up on the screen

To turn off those "options" that show up (and usually automatically replace for you) along the bottom of the screen while you are typing:

- touch the tiny picture of a keyboard in the bottom right corner of the screen (to the left of the clock)
- touch "English (US) Android keyboard" (it should be the top option)

to turn it back on, just reverse this process
