I wanted to use use evernote to collect information for an app I wanted to make. I can not comment on their iOS and Android app but their windows phone app definitely needs a lot of improvement. No matter how many syncs i do on both my mac and windows phone, the notes entered in the respective devices won't sync. I really wish MS releases their One-note for Mac. The way their one-note app on WP and windows 8 syncs is amazing.
