It functions fine, is 7-8 years old, and lives on a construction site. Might give her a once-over whenever I work in an office again but for now I don’t mind. It’s all dust and dried mud anyway, not greasy fingers

Okay I was gonna comment the same thing but if it’s on a construction site I get it and even more a testament to its but it for lifeness

No worries! Didn’t mean to come off brusque, just wanted to clarify. Definitely a great piece of equipment

That makes sense then but it's screaming for a wet wipe or something

I'm thinking Q-tips dipped in alcohol for those tight spaces between the keys.

I don't know what Texas Instruments is doing, but they're killing it.

This calculator got me all the way through 2 years of high school, 4 years of engineering in college, and so far 2 years of construction management. It's therefore 7-8 years old, has been on numerous jobsites, has all the necessary tools to get through every math class I took - trig, algebra I and II, Pre-Calc, Calc I, Calc II, Calc III, and Differential Equations. Just last month it was in the muddiest excavation I've ever been in, under blaring Pacific heat, and I could dependably use it for weeks without a recharge. By the way - either the battery or power consumption is incredible - my biggest stressor with this calculator is that I practically never have to charge it so I might lose the charger. That's it. The color screen makes multiple graph functions easily navigable, its software is highly versatile, it fits conveniently into pockets (much slimmer than standard TI-84's), and overall has been an amazing implement to have in my education and work.

Ill probably buy another one when this one dies in 10+ years

I've got a ti-nspire with the same story. I've replaced the rubber feet and the battery, but short of that its in fantastic condition.

Agree. I have a TI-83 from 1996 that I still use nearly daily.

I wish I still had mine! I got a TI-89 when I started high school and was taking more advanced math classes and I don’t know what happened to my TI-83. I miss the built-in screen protector.

Makes me feel old that this is a “buy it for life” post on a product that didn’t exist when I bought my standard TI-84 in Algebra 1 which is still kicking it by the way lol. My wonderful TI-89 lives on my desk still used daily and that was bought in 2010(?) now I feel old

I have a ti-89 from either 2000 or 2001 and it still works perfectly. Really well-made devices. Also have an 82 from the 90's somewhere I should dig up, that thing was as rugged as the old Nokia phones.

Ha! I still have a TI-85 from 1992 and it still works.

I have one and the ceiling collapsed and flooded onto my desk at work and it still worked after that. They are tanks

I have a TI-81. That thing came in clutch while I was pinching pennies. Grocery shopped while adding up everything then added in the sales tax. Also worked great to keep my scouts within budget while shopping. Still prefer it to adding up things on my phone or computer.

Not particularly. Traded it for a standard TI-84 with another student bc their teacher wouldn't allow the Plus, ended up never trading back

Amazing how little these have changed over the years. Including the price. I feel like they should be much faster and cost $50 tops

GlampingNotCamping OP t1_j4vtcef wrote

TI is functionally a tech company. There are plenty of companies out there that simply produce calculators with stagnant tech that do 90% of what people need a calculator for. The extra cost covers the last 10% and that's all R&D for batteries, software, and supporting platforms. Production of the device alone is likely much less than half the cost

Nope, I run a tight ship. I clean this thing often, it just spends a lot of time on dusty, muddy, or hazardous jobsites currently so keeping it clean is pretty low.priority

Tried it but ended up being more annoyed. Ti36x pro is dope though.

TI makes great calculators, but I was recently given a new 84-Plus CE and I am definitely not a fan. I absolutely cannot stand the change from AAA batteries to only having a charging cord, and the slimmer design seems like it makes it more annoying to slide the cover on. I also don't like that they reversed the orientation of the cover, so now you have to slide it on from the top as opposed to bottom. Also, maybe it's because of the slimmer design, but the buttons feel very squishy to me. The buttons on my old 84-Plus feel like there's more weight behind the press, while the buttons on the new one feel like one of those cheaper scientific ones where it might miss a button press every once in awhile if you didn't press it really deliberately and with enough force.

So personally, I'm sticking with my old 84-Plus for now, but that's just me.

I don't mind li-ion batteries. Like, 10440 cells are same size as AAA but last waaay longer (4.2V vs 1.5V - you can store more energy at higher voltage...) and are easily rechargeable and don't leak, stay charged longer etc...

I just hate when it's a non-replaceable format which is common nowadays.
