12key English inputting
How about provide the 12 key English inputting. It reminds me of the good old days with the old 12 key mobiles, and so big thumb friendly.

Use "Japanese 12-Key", its surprisingly usefull, as it allows to enter latin alphabet using standard ITU-T layout, allows left+right cursor arrows and its simply wonderfull. Lets try it, even on WP7 :-)
