Notepad computers don't kill people, worst case your stuff doesn't work and they won't use it again.<p>This is not 'mission critical' by a long shot.<p>It all boils down to the safety vs freedom argument, we can be 100% safe or we can have a lot of freedom. Personally I'll take the freedom, if you want to be 100% safe but only able to run vendor approved applications then that's fine with me, but it is one step too many in the direction of 'trusted computing' for me.
