For the record: the keyboard mapping of the (classic) emulator is a big PITA, I think. Don't expect to press key "A" when you type "A" on your PC keyboard...#-)

The 31s does a much better job here. And maybe that's more of an everyday calculator, compared to the 34s. Actually my Windows "calculator" hotkey pops up the 31s emulator. ;-)

In a way this really is true. ;-)

This calculator isn't meant for easy equation solving (It is not pick up and play at all (except for basic RPN calculations)). It is meant (ONLY) for repetitive tasks that can be programmed and it is a standard RPN scientific calculator besides this.

Quoting John F. Kennedy: "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard". That's what the 34s is made for. It is a calculator that can do things no other calculator (I know of) will do out of the box. And not with this accuracy (up to 34 digits, even with exotic functions). Whenever I need a reference it's the 34s that I use. Another example: I have designed some rational approximations that approximate the Normal quantile function with 10+ digits. This means solving a linear equation system with 9 unknowns. Try it in Excel (which I normally use for such things): no way, the roundoff errors with 15-digit IEEE double precision make the obtained results unusable. Solve it on the 34s, and everything is fine.

Yes, this is a limitation of the 34s programming model. But more important, even in normal calculations you cannot enter more than 12 digits ("Too Long Error").
