this is a really large frustration of mine...they often don't predict what i'll type next, and i accidentally select an option then i'm hitting back to delete some large phrase it selected... argh, this and auto correct... so much time spent hitting delete... I feel like this is something trying to be too 'intelligent' for it's own good
