I got Casio FX-81 as a gift in year 1981. I am using the same calculator for almost 30 years. Also, I changesd the orignal Casio battery only around six months back! What a wonderful engineered product.

Are you sure? I purchased an LED based TI calculator in the mid 80's. Very expensive and ate the battery. When were LCDs in common use?

I bought one of the first HP-55 programmable calculators in, I think it was, 1975. I had to send it in once under warranty, to replace the super-cheap power switch, which was a slider making contact directly on copper traces on the circuit board! But, otherwise, it was a great calculator: Over 3 hours between recharges of the NiCd battery, and it combined a programmable calculator and counter/timer.. After I upgraded to an HP-67 (same stupid power switch!), I soldered an electrolytic capacitor into the battery compartment, and I still use it that way, with power adapter plugged into a wall socket. But, I don't calculate any more with the HP-55: I've had it continuously turned on, with the counter running for over 30 years now, as a way to detect whether there has been a power failure while I was away at work. If the count has stopped, or the display is garbled, I know my AC line has gone down! They don't make them that way, any more.

P.S. Its more than 2 decades -- TI-30s were available in the late 70's.

It should not be too surprising when you consider the magnitude of the TI-30 and TI-80 series marketing collateral. Having supplied algebra and mathematics textbooks to almost every public school and many colleges in the country, textbooks that just happen to include keystroke-guided how-tos, it is no mystery that TI is inclined to continue with the form-factor and user interface. Because of the successful effort embedding their product into the curricula, TI calculators are now the defacto standard for what-to-buy lists in most school districts. Hats off to the TI guys that thought of this; our "educators" bought it hook, line and sinker.
