Former DPT-S1 lovers: Should I upgrade to RP1?

[gbgbgb]

I can still easily find technical reviews from when DPT-RP1 first came out, inc a video of it next to DPT-S1.

I am however curious to hear from long time owners of DPT-S1 like myself, who made the switch to DPT-RP1, and have now been using the new device for some time.

I love my S1. Sure, it's a bit slow. And I only sync it thru the clunky mount-umount USB cable. But at the end of the day it is pretty wonderful. I love writing (and erasing) on academic pdfs with it and I do a lot of it.

My questions to those of you who have taken the leap from a beloved S1 to RP1:
1) Having had your RP1 for a while now, would you advise me to buy it?
2) What would be the best part for me about the switch from S1?
(The worst I'm guessing is a $700 hole in my pocket, and maybe clunky upload-download software).

If I have missed previous similar discussions (not spec comparisons; S1 users switching to RP1), please feel free to share links.

Thx!
