Actually, used HP-15Cs can sell for hundreds of dollars since they are highly sought after. So $100 for a limited edition run is not too crazy.

Although purists may still want the original since the new HP-15C appears to be using an ARM processor to emulate the older Voyager hardware.

BTW, HP is also releasing a HP12C 30th Anniversary edition.

If you think that's exorbitant, you should check out the $29.99 iPhone app.

True, www.hp.shopping.com lists 15c at the same price as the TouchPad. Even so, I am thrilled.
