You won't use A2 refresh mode. I promise you. Unless you like looking at layers and layers of half opaque garbage.

Google Drive/Docs should work fine for whatever you need. And you can always install the Google "swype" keyboard, which is actually amazing on this device. I posted this video a while back. Again, this video is regular refresh, not A2:
