Just received a HP35s

[Derek W]

The 35s has been my everyday calculator on my desk since I bought it in around 2007. I prefer its 2-line display to the single line of my 15CLE, and it's less cumbersome for run of the mill calculations than my 50g.

Some users have reported heavy battery consumption, but mine is only on about its 3rd set from new. Most of the items in the bug list don't affect the sort of work I do, but the one that does annoy me is the disappearing exponent for numbers <1 in ALL mode (no 9 on the list). As an engineer working on practical projects, I rarely need more than about three siginificant figures in the mantissa, but an error by a factor of 10 could be serious.

I think the hardware quality is very good, it's just a pity that the firmware bugs couldn't be ironed out, for contractual reasons that Tim W has described in earlier posts.
