Re: What's the longest you've used a particular graphing calculator on a regular basis?

Generally, each time I've gotten a new calculator, it quickly became my main one, and I no longer used the older ones much. (Nowadays, there's an exception, where I currently use both my TI-89t and HP 50g often.) So the breakdown becomes:

TI-81: A few months to a year?
TI-82: About a year or two
TI-85, TI-86: About three years each
TI-89, TI-89t: About 5–6 years each

So the winner will soon (if not already) be my 89t, since I use it more than my old, battered 89.

Well I have my periods where I don't go on any calculator, so I'm not sure yet what to answer.

I only ever use one calculator at a time. I've hoarded all the old ones though. I've used the following extensively:

Casio FX-4000P 1986-1993 - 7 years (at school). Not graphing but worth a mention.
TI-82 1993-1997 - 4 years.
TI-86 1997-2011 - 14 years
TI Nspire CAS 2011-now
Also use a TI-92 (not plus!) on and off that someone gave me but I just can't get on with it as you really have to lug the manual around.

I've spent less than a new TI-84 on all of the above together.

That's incredible. Still working, eh?

How long have you used it for programming?

-lasted through a few years of heavy use (2009?-2012), now even setting it down makes some power connection inside the case fail and crashes it x.x

9750gii/9860gii 2010-2011
-used for math, equation solver & co.
-also eventually for a faster-running FPS :P

Prizm 2011-Current

Used a TI-85 for all of last year in school and this year I'm using a TI-86 I picked up. Also have a TI-83+ but that and the TI-85 I use as loan outs for now, people seem to want an iPhone over a calculator (and I would rather the 1-3 TI-89s or maybe even HP 50Gs for the same price).
