I am running two HELM devices and have a lot of different clients in play (phones, tablets, etc.) For those using a PC I have been leaning toward EM. For those using various android devices I really have not found a preferred answer. Me personally have been happy with the native email client on my samsung hardware.
So to the few of us here - what email client would you recommend to an android user who is getting email, calendar, and contacts from a HELM device. (Note I stay away from outlook due to calendar support)
