For me it was a choice between this calculator and a TI-83+. The fact is, this calculator has many more functions and is a lot more user freindly then a TI-83. For instance, unlike a TI-83 or TI-86 you can solve for x in an equation like 5=x^4+(x-3)^3. The HP39G divides each type of fuction into different "applets." There is one for stats, one for polar graphing, one for solving, and many others. The only bad news about it is that it's slow. It seems to take about the same time to do a very complex equation as to do 1+1. Don't worry though, you get used to the little delay-- it's still completly worth getting this calculator. It's cheap, there is plenty of games for it on the web, and it's fully featured.

As a high school student the hp39/39/40 series seems to be the best around in this price range. Similarly priced TI models only have 32kb of memory, while th 39g has 232 available to its users. Ive been using the 39g for 2 years now, and its absolutely excellent. Many people have commented that its slow, and i agree, so the solution is to have a common scientific calculator for basic functions (esp fractions and RA trig...) and a greaphics for everything else. This is the quickest and best way of operating, and scientifics are only about $15. The PC connector cable is a must to 1. backup data and 2. download notes, aplets and games from the net. Also to create notes on the pc (heaps better than typing on calculator!). Um yeah, buy the hp39g (or actually, i would buy th3 recently released 39g+, which is the same but with a finance aplet and about 2-3x as fast, esp graphing)

1) This calculator is slow. Any operations require a fraction of second for it to "think".
2) It only comes with very few e-lessons. No more e-lessions available from HP web sites.
3) The infrared port is useless. I couldn't share data or programs with anyone. Very few people are using this calculator.
4) The cable which allow this calculator connects to PC sold seperately.

I am very pleased with my purchase. It was my first time to buy anything from Amazon so I was a little aprehensive. I am pleased I did. I got a great price and it was shipped very fast. Thank you!

....

This calculator is really bad. it requires about 1/4 second delay for every simple calculation(e.g. 1+1=2, 2*2=4). it takes even longer for a more "complex" calculation (e^x, log, arctan...).

I'm am engr graduate student at Penn State. There are lots of HP equipments in my lab and they are great. I just can't imagine how a HP graphing calculator can be so slow. ...

i give it 2 stars because it's light and fancy. but if you are a serious calculator user, forget about this one.

I bought this HP calculator not to long ago, and all I can say is that HP did a great job. Me being a math major in college, I needed this Calculator. This thing has more functions than a fighter jet. One of the best features on this calculator is that with it's infrared port you can send data to other people that have the same calculator. Another great thing is that you can hook it up to your PC. I love this calculator, and if your in High School or College, you must buy this. The Best Calculator ever.
