Found it really annoying that every key press created a beeping noise to let you know that you press a key.

Or it ignores my key presses and does its own thing

The keyboard often, though not always, misses your first button press.

The halo keyboard is also nice to have as when it is flipped in tablet mode, no keys are sticking out and the keyboard "shuts off" so you don't have to worry about accidental key presses

Great e-book reader for B&N users.

I love having a great e-reader that turns into a laptop with a keyboard and enough screen real estate to do any kind of computing that comes to mind.
