already have a ti 84 titanium sorry.

and the battery. i would say with daily use of around 2 hours the 4 triple a's would last around

2 months maybe 3

i havent changed the batteries in 5 months but i dont use it every day.

 
I can vouch for this calc. I have one and used it for Calc 1, Calc 2, Physics, etc. This thing makes the work load so much easier. Pretty much solves problems on its own. A lot easier to use than the 83s and 84s IMO.

 
I feel you on that thing being complicated... I just use a regular little ti-30 scientific and have made it through calc 1 & 2, and physics 1 and 2 the HARD way.. Bump to try and help make someone's life easier.
