yesterday i was writing email with my new bluetooth keyboard and i realised that, words are appearing on screen after 5 seconds delay. first i blamed new keyboard and replaced batteries. then blamed chrome and checked memory/cpu usage all was fine. then i wrote email in vi and paste into gmail, even select old text and paste was extremely slow. thanks i saw this post, you are right it is almost unusable.
