Was searching the HP home site and came a across a photo of possibly a new HP calculator. It's light grey and has a small solar panel. The photo is on an angle so it's difficult to see the key layout. Hopefully this a cheap RPN pocket calc. If the HP-12c appear first, just click on the number 2, and the photo should show up.
