Fun idea. But the problem with these things is that you need to keep rebuying new ones.
Also, most of the problems with onscreen problems for me were mitigated by swype -style typing at which I'm faster than a physical phone keyboard now. Though not faster than a real PC keyboard which I still highly prefer when I'm at home or at the office. So I use my phone mainly for when I'm out of the house, at home I still have a PC that's on 24/7. As such I'm not really happy with the mobile-first attitude of most services but what can I do :)
