I received the upgrade this afternoon. Still is flaky with the keyboard though it now uses the intelligent type ahead and highlights misspelled words. However the keyboard pops up at the wrong times, and sometimes the cursor jumps to odd locations as you type. Overall I have not seen much by way of enhancements or fixes that would make me want to use it on my Playbook all that much. The Web based client seems more useful to me right now. I have not yet checked to see if it caches content locally or not with this upgrade in case you have no Web connection.
