Help me pick a calculator! (in Off-topic)

I'm trying to pick a calculator for school. I've decided on either an HP 50g or a TI-89.
So, if you were in my shoes, which would you pick? I'm leaning towards the TI-89...

I liked my 89 TItanium, but that 50g has an SD slot, which I would've liked for the 89, not much memory for those things.
I don't know anything about the 50g, but i did like my 89.

We bought a TI 89, the person that used it really liked it but said it is so powerful it could not be used on some tests like the ACT or SAT. Though the TI 83plus (i believe) was OK for tests.
When I was in Engineering school we used a lot of HPs and they were great - i would suggest asking a teacher that teaches math or Physics or whatever classes you will be taking to see if they have a preference.

I vote TI-89, only because my old abused TI-85 wants me to come play with it again.

Picked up my "top of the line" TI-80 that i got when it was brand new, and forgot about a couple of the programs that i had written on it. hadn't touched it in like 5 years, it was like WOW

89 cause it's a better calculator.

50g is the better calculator for pure math. It is far more flexible and programmable not to mention better specs. If you use RPN, the 50g is infinitely better.

89 (or 89ti) is better for just general usage. Its learning curve is less steep and it is far more user-friendly (I had an 89ti). Far more schools use TI calculators, and if you want programs (games or whatnot), 89 is the way to go.

Go with the TI. It can play Super Mario :P

The TI-89 is great. Very user friendly and still quite much in-deph things.

get this one: http://education.ti.com/educationportal/sites/US/productDetail/us_v200.html

Alright, well, thanks guys! The TI it is.
Also, Henk, I was considering getting that one, as it's only about $20 more than the TI-89. ;)

As you can tell, most of us went through school with the TI lineup. I think I might still have my TI-82 laying around...

But if you want to impress you teacher, rock out in Calculus class with this bad boy:

I'm an RPN man, so I'd go for the HP -- have had HPs since around 1990, a 28S helped get me through college in math and physics. I thought stack-based manipulation was silly for the longest time, until I started using it. Then I REALLY started thinking like a computer. *smile*

But the TIs do look sweet, and they seem to be the preferred tool in education circles...

I remember my first programmable graphic calculator.

It's was lots of fun, until Teachers caught on you could use its programable memory to store formulae. >;)

My teacher never figured that out ;-)

Just don't pay more than $100ish for the calculator. Amazon sells them for $140, but I'm sure you can find them for far less on other sites like ebay.

Actually, I did a little digging, and found that the TI-89 is not banned on the SAT.
I'll have to be careful I don't make it a crutch, though. ;)

I used to have a TI 92

The TI-89 also handles units, which is a godsend if you're doing physics and you need to do a quick sanity check.

Ti-89 also has the "solve" function, which can solve algebraic equations.
