The Eseries business line from the Finnish giant features practically every possible keyboard layout: there are candybar and slider phones with numeric keypads and full QWERTY keyboard, and E90 has a large full keyboard in a clamshell form. E55, pictured below, has been approved by FCC in America, and it's a handset slimmer than phones with a full keyboard and still offers a relatively comfortable text entry method, as there are only two letters on a key, so the number of mistypes and keypresses can radically decrease if you don't use lots of special characters.
