I am nervous, because I know that every time I update my 34s, I first have to kill it! ...
I plan to mod the unit with crystal and caps this week, and then another 'erase' flash cycle! Thanks again for everything/ The WP34s is quickly becoming my favorite calculator ever. Its faster than the 50g, its more fun than the 35s, and it leaves my TI units in the dust.

Don't you be afraid. Flashing a WP 3xS for updates will happen frequently, thus your nervosity will decrease continuously following e^(-t/T_0). And thanks for your kind words.
