I'd rather wish that Christopher had worked on his NP41v3: mine still remains an unusual paperweight once its boot sector got damaged after a firmware upgrade...

I saw this on the FB HP Calc Fan group. It was hard to decide which one to buy, the one with the bubble LEDs, or the much cheaper one with modern LEDs. I still haven't decided... but will probably go cheap on this one...
