Trouble with my Blackberry Storm....

I used to have a Blackberry Pearl a few years back and the cursor ball would always stick, it would also turn off all the time too. I hated it and was happy to get rid of it! Now I have a Blackberry storm and guess what....? It turns of by itself and it freezes up on me too! This is supposed to be a phone for people with businesses? You would think with as much as we pay for phones, especially for the Blackberry users the glitches would be no more by now.....
