Nope. Really no change from the previous Notes. The Wacom pen designed for the Notes are around $40USD. And their other pens are more expensive than this. My Intuos Pen would cost $80USD to replace.
@Vic20: Do you know which model you have/where I could buy one? I also have an old S pen with eraser that has worked with every Wacom device I've had, except the Note 8. The phone doesn't recognize it at all, nor does it recognize the S pen from my Note 3, so somewhere along the line they changed something.
I have the Note 2 S Pen, first Note 10.1 S Pen, S Pen with eraser (for Note 2) and MS Pro Pen (for MS Surface Pro 2). These work okay with the Note 8 but not perfectly. There is an offset with the pens and sometimes doesn't register. I think it's more due to pressure sensitivity on the pens and screen digitizer. The Note 8 has 4096 levels while the pens I have are 1024 levels. These pens I have are no longer available and probably discontinued. You'll probably find them in the secondary market.
Thanks for the info. That's funny, since I also have the S Pen with eraser for Note 2 and the Note 8 doesn't pick it up at all. Must be slight differences in the way different units (of either the pen or the phone) are manufactured. Maybe I'll try to pick up an old MS Pro Pen and see if that works.
