To make matters worse, the sensors on the Nexus One for the four
hardware buttons are not exactly aligned with the silkscreened
icons. You have to tap noticeably above the button to get it to
register. That was very frustrating for me until someone (from
Google nonetheless) pointed out the mis-alignment. Up until then,
I consistently had to hit the buttons three or four times to get
it to register.
But even worse than that, the home button on the Nexus One is
right below the fracking space bar on the portrait keyboard.
Combine that with the not-completely-precise touch screen, and you
have a UX disaster. I can’t tell you how many times I’ve been
typing and ended up leaving my application due to accidentally
hitting the home button. Leaving an application mid-sentence is
hardly a good user experience.
He’s got lots of other observations I agree with, but the above one is, without question, the biggest WTF on the Nexus One. It’s just bizarre.
