Your First Handheld?

[Tugdual]

I started with a TI 57. Even passed exams with that... what a fool I was. The battery could hardly last for 1h by the end of the school year, keys were bouncing and pi would become 33333.11111444441111. A nightmare. That year during vacation, I opened it and found a nice RC network that I immediately changed to alter the clock. Was hilarious to torture this poor little thing and when I was fed up testing the various speeds and see its segments blinking like crazy I decided it didn't even deserve to be reassembled. Not sure where it is now. Found one for less than $10 on ebay, so it didn't even get value with time.

The year after I had a 15C. Nice and clear LCD screen, infinite battery life, complex numbers, matrices, solve, integrate, factorial (on non integer values yay excitement, discovering gamma function), linear regression, stats, huge memory (yeah different perspectives by the time), great form factor, very solid design. Took me a very short time to get used to RPN and now I find it hard to use non RPN calculators (like the Prime...). If you ask me, the legendary calculator from Hp is the 15C and I recently purchased the LE. I enjoy it even more for the speed and if the design is inferior to the original one, it remains not bad.
