One of the primary reasons I bought the Surface Pro over a convertible ultrabook like the Dell XPS 12 is access to the digitizer pen for taking handwritten notes in OneNote.
But I have found that because I can type so much faster than I write, I am rarely using the pen for inking. Also, obviously because my handwriting isn't the best, search accuracy at a later date will be more accurate with typed text. I find myself using the pen less for writing and more for diagramming, a task which could be easily handled by a normal stylus with a finer point which are commonly available today.
So, I am torn. I suppose that it is nice having the pen there in case I have to scrawl down some handwritten notes quickly and I don't have access to both hands to type - for example if I am in a restaurant on the phone and I don't have on my bluetooth headset and need to hold the phone with one hand as I write with the other.
So, glad I have it, but don't use it nearly as much as I imagined.
What's your experience?
