Just thought I'd let you in on well the simple things in life satisfy. So I go to change the batteries on my TI-89. I feel a hint of nerdiness havingto change the batteries in my calculator. I thnk I replaced them just a few months ago...but anyway. I change out the batteries, and turn the thing back on, and I couldn't adjust the contrast (I am stupid, but I'll tell you why in a sec.), so I am thinking, maybe there is something wrong, and if I just pull the backup battery, maybe that will work. So I do that, and CRAP, my computer throws an error code. Now I can't do anything. So I call up tech support. They are quick to make me feel stupid as they tell me how to fix both of my problems in under a minute. I feel dumb, but at least there are some helpful smart guys at the end of this telephone line. That's more than I cann say for a lot of companies. That is all. I'm off to get my free jamba juice and keep my good day going strong.
