Everyone is correct, the screen needs a bit of break in time, I had the "tacky" screen for about 2 days. I have been using this for college, electrical engineering, and this has been an absolute pleasure. There is a learning curve. I feel like I'm in the manual more than I've ever been with a device, but that is part of why I wanted this. I tried an Ipad, ew is my opinion of that now.
There is a LOT of built in features. Some like the two fingers on the left slider work magically. Some of the features, not so much, mostly within PDF's, which isn't its main function, but still. The two fingers on the screen, eh, sometimes it registers just fine, some times, my fingers are okay just needed to drag the eraser from the center of the screen, other times, I give up and manually select the eraser. Very frustrating. The registering of the zoom, forget it, half the time I end up clicking the zoom out button, or spend 30 seconds zipping around the page because it doesn't auto refresh when you move in the pdf while zoomed. However, PDF uploading is a side feature and if you are a little patient, it's absolutely fine.
The built in calendar, one of the best, yet very disappointing aspects of the Supernote. There is a month view, you can write there, itty bitty, but you can. Theres a week view, very, very nicely spaced for those quick notes, dr apt, call back, check in ect. However, even though there is a day view, can you write there? Nope, you can however, take 3 years out of your day and type it out, you get my point, we should be able to write here. They are working on it though.
-TLDR-
Screen needs break in time, but still feels great out of the box.
Syncing any of my college PDFs, extremely easy, literal drag and drop. Zoom and screen select are funky in the PDF, doesn't matter the size, but a little patience and it's fine.
Calendar, amazing, but lacks the handwriting in the "day" tab, their site for tracking upcoming additions says this is coming though. If not, work on that please.
