I just picked up my 1520 yesterday, and so far, I'm thrilled with it. Having said that, I've used convertible notebooks with Wacom digitizers for years, and inking in OneNote is a really useful tool for me in my work (client interviews in consulting projects). I take notes all day and then transcribe the notes at night in my hotel room, all in OneNote. I concluded that the tablets were too heavy for all-day use, so I tried the Galaxy Note phone (original one). Too small for note-taking and I so HATED Android for a phone. The the recently released pen-enabled 8' Windows tablets were not then available, so I've been using a Galaxy Note 8.0 for the past year. I'd still be using it if I could ink in the Android version of OneNote.
My current strategy is to use paper for note-taking, and at the end of the day use the 1520 to snap a photo of my note, paste into OneNote on my laptop, and then transcribe.
A Wacom screen and stylus definitely have their uses, but for me, I'm going back to paper and enjoying the goodness of my 1520 as it is.
