Right. I can't see why anyone uses Gmail. The built-in mail client in Android works just fine with IMAP servers. I have two desktops, a laptop, and an Android phone all using the same IMAP server. Everything but the Android phone runs Thunderbird.
It's rather nice that Mozilla maintains Thunderbird but doesn't change it much. The Firefox UI keeps changing, but not improving. Over three years, Firefox moved add-on icons from the top to the bottom, then hid them, then moved them back to the top again. I'm worried that if they change Thunderbird, they will "add social features", make it send your contacts list to Mozilla HQ for "syncing", or something like that.
