I also use a MS Surface Pro, have installed Evernote for Windows and found the New Ink Note option.
This actually works great! UNTIL I want to view that handwritten note in Evernote on iOS..... It doesn't show the content of my note.
I'm really disappointed in this since I feel that I should be able to sync and view al my notes cross platform.
I used the Livescribe pen and that worked great for handwritten notes.
Please Evernote team, make sure that Ink notes are viewable on all platforms a.s.a.p.
