Is 5 or 10 dollars worth the wait while also running the risk that they WILL be sold out? How badly do you want it?

How badly do you want it? i don't need it that badly, but eventually i will need it in the future, i went there to check they got the same quantity and the same price for it, I am just going to check every week, meantime i can also save up money to get it Science Advisor Homework Helper You didn't mention what you would be using the calculator for or what your needs are. A TI-89 could be overkill while a$14 TI-XII30 may be adequate.

the TI-89's are nice, no doubt, but there's not a whole lot more they can do than the 83. i don't think it would be worth the money for the upgrade.

by 89 standards though, that is a pretty good price for a new one.

i am having one rite now.
I bought it simply because my ti83 was broken 1 week b4 the AP test during my senior year. I passed so many tests with it. Though, i don't get to even touch it at all since that year... It is because now my calculations are done on computer and can be done on computer/by hand only...lol

I would have to disagree.

They have a built-in solver. The pretty print makes it a lot easier to read expressions. From what I understand it's able to evaluate derivatives/integrals easier. The overall feel of the calculator is better.

Those are just the basics. There are plenty of other capabilities the 89 has that the 83+ lacks for things like matrices and beyond.

I used an 83+ and I used an 89 and I have to say it just makes sense to get the 89 right away instead of spending the money to upgrade later on.
