If you still work most efficiently via pen and paper, but you also want digital copies of your notes for future reference, Bamboo Spark might be for you.
But beware, at $160 Bamboo Spark is pricey for what is basically a fancy notepad and folio, and it weighs about 1.4 lbs. (according to my postal scale), more than many tablets, including the iPad Air 2.
You also have alternatives. Livescribe's line of smartpens ($120 to $230) require special paper, but they can do cool things such as record audio. And you can always go with plain paper, regular pens, and free (or at least inexpensive) scanning apps.
