Pontos Fortes: See my comments.
Pontos Fracos: the only thing that it misses is a color display!
I used a 2-d HP graph calculator for 5 years, then I decided to get this new HP calculator that makes 3-d graphs. It is amazing how things have improved. The calculator comes with an awesome leather case. It is very light. The manual is easy to use. I use to have trouble with my old calculator having to delete all the time my programs because the lack of memory space, in this one you just need to...
Pontos Fortes: Easy to use
Pontos Fracos: None so far
I have purchase this item from Amazon.com. Luckly, the price was so great at that time. I only pay for $77.99 for this high quality product. Vey happy with its performance!
Pontos Fortes: Included all of the same features that I depended on with my old (now dead) 48G.Faster than the 48G.Nice readable high contrast display, with 7 lines of the stack visible. SD card slot.Hinged keys
Pontos Fracos: Ever so slightly wider than the 48g, but noticable. Really that's about it (after a week of use). I would have liked a bigger "ENTER" key.
My 48G died after many good years of service. I read the bashing that the 49g took and was somewhat concerned with the purchase of the 49g+. It came with the latest ROM already installed so I did not suffer through key debouncing or battery life issues that other earlier adopters had to endure. I created a user defined key to provide quicker access to the equation library (since this is now...
Pontos Fortes: Reverse Polish Notation, Powerful and fast solver, SD expansion, Large ROM and RAM capacity.
Pontos Fracos: Low Resolution, Keypad made of rubber.
If the HP49G+ has the screen and button of TI-89, then it'd be a perfect calculator. This calculator is over a very very powerful one, but how study is it? We'll see as time goes by.
Pontos Fortes: Design, material, content, SD card, USB interface for update
Pontos Fracos: monogromatic display
This piece of technology is everything an engineer student needs. What is realy apealing to me is the SD card that can be attached to it, in a way that you don't have to delete old stuff due the lack of memory space and also the USB interface once you can transfer data from your laptop to your calculator and vice-versa. HP also promisses to make updates on its software online. As technology has...
HP49g+ Graphing Calculator F2228A : Very good. The shipping is very fast. The price is reasonable. It is a good and powerful tool for engineer or scientist.

HP 49g+
Pontos Fortes: Big, easy to read screen, fast 3d graphing, no missed keypresses, and a SD card slot for practically unlimited expandibility.
Pontos Fracos: The hinged keys can be hard to press, and the SD card slot may require fiddling to get a card in.
If you want the most powerful calculator available, this is it! However, with that power comes a steep learning curve. Plan to spend several hours finding your way around the menus and becoming comfortable with the interface. If you do not have time for this, then this is probably not the calculator for you. Although earlier batches of this calculator had some issues with the keyboard, I have had...
