Google seems to want to frequently re-invent common idioms willy-nilly. They've had several iterations of email client for Android, from the AOSP client to Gmail to Inbox. I don't want a learning curve, just a mail client. (K-9 or Outlook for Android, cheers) They've also had numerous goes at creating a sms/xmpp/talk/video app. Google Talk/Allo/Duo/Hangouts, it's all a confusing mess.
