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...

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... --Bob Prosperi |
