The HP A10 Printing Mailbox for Presto Service is really a great idea. I had a similar one about 10 years ago. The concept is for those, like the WW2 generation, who might never have gotten into computers, or at least not very deeply, and yet you might want to be able to email your grandparents.
This device plugins into the phone line and dials into the Presto service a few times a day, and prints out any received email. It uses a whitelist for screening email so you won’t get printouts from any spam or junk mail. Though it is a great idea, I have to wonder how long the Presto service has been around. The target audience for this device must be shrinking every day. Still, I applaud the concept.
