Yes I've got a similar system setup, you only loose the offline feel. Using a tablet with handwriting recognition is still slower then the typing it manually, also moving tasks to the next day or week is easy with org-mode. I now have a little index card for fast note, task and event capture. An e-reader with orgzly to edit the org file for the day and a list of MITs on my pebble watch ready to be checked off P
