How do you like the Woodstock calculators?

Being a desk worker I've never really considered that. But for the fun of it I've just went through my small collection of HPs and among them the 25 is indeed the only truly comfortable "one-hand" machine. Of my other machines, the Sinclair Cambridge Programmable is is the only competitor, even smaller yet with large enough keys. However its many cons put it far behind the twenty-fives. A cute calculator nevertheless :-)

It had two interesting side effects: one, the calc with the LiPo module is lighter than a HP-25 with NiCads or alkalines, so it's more likely I'll have it with me, and two, the pack works so well that I actually rarely have to worry about charging.

Brilliant! I wish I could make something like that. Unfortunately my "handicraft" stops at building snowmen...
