Oh wow so when the weather is cold I won't be able to log in because of my cold stiff fingers that type at a fraction of the speed, possibly with increased mistakes because the up-down movement comes quicker than the left-right movement?
What if I come home drunk and feel the need to post a social networking message that I'll read the next morning in horror? Wait, I guess that won't be a bad thing, increased mistake level will block me out. Winner!
