Is a spare 35S a good idea or redundant?

[Matt Agajanian]

Hello all.

I was considering the possibility of purchasing a spare HP-35S. Since I have a 35S I bought a couple of years ago, I'm hoping HP has addresses the firmware glitches since my earlier purchase.

If the programming, calculating, and accuracy hiccups have been cured, I might just buy one. So, has HP smoothed out the bumps?

Thanks
