I spent 20-some years as a loyal TI customer (57, 58, 85, 86), and I agree their texts and the books written by outside agents are superior to most that are available for HP products.
Grad-school gave me a chance to re-think my loyalties, and I made the jump to RPN/RPL with a HP-49G. I can't imagine working with another calculator! It's top-of-the-line.
I couldn't have gotten over my TI habit-pattern without the help of an outstanding pair of manuals from an engineering/science instructor with a penchant for HP calculators (the 48 series in particular). If this type of documentation was available with the high-end calculators from HP "out of the box", I think they'd have many more converts and satisified customers!
For those who care:
The manuals are written by Gilberto E Urroz, PhD, PE (this guy is my hero!) -- and can be obtained on the net at greatunpublished.com. Titles are "Science and Engineering Mathematics with the HP-49G", ISBN 1-58898-043X for volume 1 and -044-8 for Volume 2.
Caution: The manuals are RPN/RPL focused, so if you're planning to use the '49 in algebraic mode (I don't recommend it!), these probably aren't for you.
They run about $25 each for hard-copy and $20 in electronic format (which they'll e-mail to you). If you buy hard copy, you may also request electronic format for no additional charge.
