I cba to carry an extra accessory to be honest
Since it fits very nicely in its slot, you don't need to carry anything extra.
For me, the S-pen is awesome. Presently, I have the original note. Also, recently, I got the note 8, from ebay. On both, the s-pen works great. In meetings, the note 8 is nice to have for taking notes. Many ask me where they can they get one. The split window, navigating, etc are nice, but I use mine more for writing and drawing. Lots of uses...
Luckily, I got it brand new for $265 (as luck would have it, paypal gave me a nice coupon plus the seller was discounting it). After receiving it, I registered it and got the $25 for the play store. Even though you may not get it this low, there are very good deals where you can get one below $300 (used but in very good condition).
Since the note 8 is so light, holding it while writing is very comfortable. Writing on the surface tablets while holding one is way less practical.
Now, I can't wait for the Note 3!
