The Note phones are the only real options for device with stylus that I know of. You can buy stylus but other phones are not optimized for such use. In re Note 4, personally I'd be happy with the usual increments in screen and performance but I'd really like improvements to camera (especially resolution and low lighting performance). Also, it may be that the biggest impact in future Note/android phones will be the Android L OS which, as I understand, will allow for many improvements to UI (like more swipe options and card layouts of running/recently used apps for example) as well as ART. The only remaining major downside may be how android handles multiple tasks... oh yes and, I forgot,... privacy...
