I have never cursed at any device as much as this one.

1, the idea of a lock is that it should be inadvertantly unlocked.
if you put it in your pocket it unlocks if you bend down.

2. button reponse is slow and variable.

3. you have to be looking at the screen and have patience. All operatinos work like this:
Press........watch the screeen to see if it takes.........Press again.

4. the only reliable operation is holding down the power button to turn it off

5. it takes several minutes to boot.

6. they overloaded the power button too much. You can never lock in one try. If you try to hold just a little longer, it turns off. HA, HA, #5 wait for several minutes.

I agree!
