iPad + S-Pen would be the ultimate win, would kill the galaxy note series in one fell swoop (coming from a Galaxy Note 8.0 user). This however looks to be the next best thing, would love to see it compared to the S-Pen in terms of accuracy and lag. If it's only usable in Evernote, that'd be fine by me, though it never hurts to have added functionality.
Coming from a Note 2 to iphone 5s I disagree with your comment. Apple needs to release a S-pen like device with full OS integration; not some third party app developer supporting just a handful of apps. The s-pen is the heart of the Note series, pulls right out from the body and does not require batteries.
I would have gotten a Note 3 but I'm tired of rooting/hacking my phone in order to have the latest software or remove bloatware that carriers love to add. If Android oem's updated their software as quick as Google releases it I would not have an iphone. I would have gotten a Nexus 5 but some how Verizon was able to mess that up.
