I use the password policy from Zenworks for Handhelds. The small keyboard
on the device is too small so I'll have to use the stylus. Also some
devices (Htec TyTn) have a physical keyboard and most of all I need the
keyboard to tick in my password. I use both my hands for this. Please
change the loginscreen with big numbers/letters, so I can give in my
password with one hand. (Like the softwareproduct Afaria has it. You could
add the functionality to add letters to it)
