I did know of its drawbacks beforehand — e.g. no physical buttons, not waterproof. The page-turning response/refresh time is noticeably better, but I'm left feeling pretty meh by the overall experience. I haven't had much need to scribble notes so as of now, the Scribe is basically an iPad-sized device with the limited feature set of the Paperwhite.
The size is good for textbook-type material, but not enough to make me pick it over an iPad if I'm traveling. The Oasis is small enough that I can carry it in a coat pocket.
But the buttons really are the killer feature. Being able to disable the touchscreen — especially when I'm anywhere where moisture is an issue (at the beach or gym) — easily makes the Oasis worth bringing even if I could read on my phone. I would have easily gone for a new version of the Oasis but I guess consumers haven't shown enough interest in paying extra for a button interface.
