My phone.
My phone my phone my phone, oh how you irritate me.
That I specifically mail-ordered you from a different country, so promising did you appear, is now something I am deeply, deeply ashamed of.
1: You turn on and off at will, owing to the fact that your on button is like any other.
2: This wouldn't be as bad if the lock button was something that was reliable, however it is also activated by holding down a single button.
3: You make a loud noise when you turn on. There is no way of disabling this feature. Not good for one's nerves when at concerts.
4: You can only display six characters on screen.
5: I cannot capitalize, nor can punctuate beyond commas, periods and question marks.
6: Your interface is generally quite irritating.
7: The clock resets itself about 50% of the time when I turn you off.
8: The alarm does not work when you phone are off.
9: The clock seems seems to be loosing one minute each day, even when left on. I have no idea how.
10: Sometimes, even when I'm doing nothing, you just reset.
I second your bah humbug A!
