Excited about this. I love certain things because they simply last forever and do what they are supposed to. For example about 18 years ago I bought 2 HP12c calculators when I started working in finance (One for work, one for home). Not only have they not broken, but I can't tell you the battery life because they are both still on their original batteries. Now old hands tell me the new modern 12cs (like mine) aren't a patch on the original and the old ones from the 80s had even better battery life than that.
