"Old," but Not a Dinosaur
2008-03-01I just recently (today in fact) obtained a like-new HP48GX. I had never used a Reverse Polish function calculator before, but after playing with it for a few hours, I am amazed at what this calculator can do. Once you learn the beauty of the stack manipulation, you'll never go back to algebra-based competitors. Furthermore, even though the HP48GX is over a decade old, it can do things out of the box that my TI-89 Titanium can NOT do. Vector and Matrix manipulations are a breeze with this "old" calculator!
The HP48GX allows you to solve mathematical problems as you go along, so you reduce the "fat finger errors" inherent in the other competitors' designs. The only downside to the HP48GX is the slower processor and the rarity of the RAM expansion cards.
If you want a calculator for professional use, HP is the way to go. No wonder the older engineers guard their old calculators!!
The most reliable electronic device I've ever had
2008-02-05I've had my HP-48GX for almost 15 years. It has seen all the abuses that a calculator may suffer inside the backpack of a college/graduate student. I've taken it with me on several assignments overseas, has seen temperatures above 40C, temperatures below -10C and most recently I spilled a glass of water on it (by accident of course). It's still working!!! I always carry it with me... I know my laptop may fail but not my little powerful calculator. RPN notation reduces the number of operations. The functions available and the ability to plot and deal with matrices have made my life easier (as a student and as a professional). After I spilled water on it I was thinking of buying an HP-50G... but my HP-48GX is still alive and has a long road to go. HP-48GX = Reliability.

Driving with a cell phone is a lot less dangerous than driving on prescription drugs
There's a lot of debate today about the safety of using cell phones while driving. Statistics show that those who use cell phones while driving cause a much greater percentage of accidents than those who avoid using their cell phones. And the studies have shown that it's not just the physical coordination required to punch numbers into the cell phone while you're trying to work the vehicle that causes accidents; it's actually the lack of attention resulting from driving and talking on the cell phone at the same time. It seems that when you're distracted, you're more likely to cause accidents.
In terms of public safety, it's probably correct to say that banning cell phones would reduce the number of traffic accidents. But I think, more accurately, it depends on the person. Some people are operating on, shall we say, lower power CPUs in their heads to begin with. They might be zoned out on prescription drugs, and when you add a cell phone to the equation, they do become a danger to the ...
