Nice but there are a zillion mobile e-mail clients already. What I really wish is a good desktop e-mail client for Linux that I can use for enterprise use: - Thunderbird is heavy, slow and the UI feels dated - KMail was very advanced 15-20 years ago but it's lagged behind and even HTML e-mail is semibroken today - evolution... well, let's say it has not really evolved in the past 10 years, since Red Hat lost interest in the desktop - others (Geary, Trojita, etc) are toys and unfit for enterprise usage
