48GX /SX Observation Message #1 Posted by Ted on 25 Aug 2003, 4:04 a.m. As a regular reader of this forum, I thought it might be interesting to 'report' on some actual users of HP calculators in practice: During a trip in Switzerland last week, I came across several people using HP 48 series machines in the world of engineering/fine mechanics. They were surprised at my interest in their HP's (all sitting next to their computers with CADCAM software), and I asked each one why they had a 48 next to their computers. Virtually all answered identically: 'I NEVER use the graphing capability'; 'The 48 is quicker and easier to use than the computer when dealing with formulas and requiring quick results'; 'Seeing the stack levels during computations is really handy and useful'; Not earth shattering news of course- but a slice of real 'HP' life in actual practice.

Low-resolution graphics Message #2 Posted by Vieira, Luiz C. (Brazil) on 25 Aug 2003, 12:37 p.m., in response to message #1 by Ted Hi, Ted; I agree with the fact that having a high-resolution graphics device in front of you, like a 1024×768 dots monitor with 16-bit per pixel, color images, with a graphics O.S. is far better than having a tinny 131×64 dots, 1 bit per pixel LCD screen. BUT... if you want your high resolution device to produce high-resolution graphics, you'll need specific SW. And if you have only the HP48, you can do graphics without extra packages, almost everything you need is already there. Of course, if you need to see a curve or parts of a surface so you can have a general idea about it, then the HP48 will probably fit your needs. Otherwise... For me,the best of all is that you can order a complete Memory Clear, dettach all libraries and you still have all graphics resources in an HP48/49. A computer, even most portables and palms, will ask for extra SW to be downloaded so you can achieve graphics. And you see, even when compared to a computer, some HP48 math resources, mostly symbolic, are hard to beat... My 2¢. Luiz (Brazil)
