I would suggest the HP-11C. It's available on ebay, and is not $15 cheap, but it is an RPN programmable scientific, of less complexity than the HP-48. I am an RPN fan, so I would go the extra mile to get an RPN calculator.
We never liked the choices available for secure email for mobile devices, because no email client with PGP encryption was available for smartphones. Instead, we had to install PGP Universal, which is a server-based version of PGP, designed for enterprise environments, which does the PGP encryption and decryption on the server, with PGP private keys stored on the server. Not a good architecture for consumers in today's climate. We strongly preferred to do PGP on the client side, but we were a long way from having a PGP client for mobile devices. And even if we had a PGP client, we would still be stuck with email metadata exposure on the servers, even with the message body encrypted.
That's why we were unhappy with Silent Mail, and why we were discussing a phaseout for some weeks before these events. The Lavabit event made it clear we could not put it off any longer.

It says "Consider a roof top coating on your car with this new material." I don't see why anyone would want that. The coating would saturate with CO2, then it would absorb no more. And it would remain on your car for years, uselessly full. How is this useful? Alternatively, what if it absorbed the carbon, then released it later, so as to be reusable? Why would that be any use as a rooftop coating? The release of the carbon would go back into the atmosphere. The whole idea of a rooftop coating for your car is pointless. Surely the scientists who developed it would not say that. Is this from a marketing person?
I prefer to see old classic films in their original black and white. I like the idea of seeing the old Star Treks in their original contexts of minimal budget special effects. The Twilight Zone did so much with so little, and that was part of is charm.

I told you why already. The wording of your posting implies you don't believe me. If you need more convincing, go to my Zfone FAQ page (http://philzimmermann.com/EN/zfone/index-faq.html ) where I address this particular question in great detail. If you still don't believe me after reading that, you are welcome to not use the product, and apply for a full refund. --prz
Although the US has ended most of their export controls for crypto software, there are still some reasonable export controls in place, namely, to prevent the software from being exported to a few embargoed nations, such as North Korea, Iran, Libya, Syria, and Sudan. And for commercial encryption software that you actually pay for (not this free public beta), there are now requirements to check customers against government watch lists as well, which is something that companies such as PGP comply with these days. PGP Corp volunteered to host the public beta software on their server, with all the appropriate checks in place. That's why you have to register, to make sure you are not in an embargoed country, to keep me in compliance with U.S. export laws. Been there, done that. -Philip Zimmermann
I wish Cryptome would not redistribute my Zfone software. This morning I had to upload a new version due to a last minute mistake we made before the release, and Cryptome probably got the uncorrected version. This is beta software in flux, rapidly changing with new updates likely, especially shortly after it hits when we discover early problems. Further, I've just added critical warnngs to my web site about how to do the installation for Windows, and if someone grabs the software and posts it somewhere else, it will lack those warnings. There are good reasons why I want to maintain control of the distribution, especially during the initial public beta. --Philip Zimmermann (prz@mit.edu)
As much as I dislike Microsoft business practices and the Windows OS, I must say that Bill Gates is one of the leading philanthropists in the world, and I admire him for that. So many of the other rich software moguls use their money to buy another yacht or personal jet, but Bill chooses to change the world for the better, in ways that really matter. When he is on his death bed looking back on his life, his humanitarian work will give him much to be proud of. --Phil Zimmermann
I went to a small school in Florida, and got a good education in computer science, in part because I could more easily get more time from my professors because of smaller class sizes than they have in the big leagues. Also, in the big schools, there is more publish-or-perish pressure on the faculty, while in the small schools, it's more about the actual teaching. Of course, you do need the degree, but I'm saying you don't need it from the ivy league if you are in computer science.
No employer has ever shown an interest in where I went to school. It's what happens on the job that interests them. At least in this field. Pursue your own self-motivated goals and don't look back. --Phil Zimmermann
Some Slashdot readers complained that FileCrypt appears to compete with GPG, which is free. Let me make it clear that my intention was not to compete with GPG, but to compete with McAfee E-business Server, for which NAI charges over $14000 per copy. I wouldn't dream of suggesting that GPG users should switch to FileCrypt. In fact, I think GPG is a nice product. But some companies prefer to do busines with companies selling commercial products. That's why NAI makes millions of dollars selling their product. There's no reason why I shouldn't try to compete in that market. And, unlike the NAI product, FileCrypt can also be licensed at a far cheaper price for users who want it on their (command-line) desktop instead of a server.
