Color-Screen TI-84 Plus Calculator Leaked
KermMartian writes "It has been nearly two decades since Texas Instruments released the TI-82 graphing calculator, and as the TI-83, TI-83+, and TI-84+ were created in the intervening years, these 6MHz machines have only become more absurdly retro, complete with 96x64-pixel monochome LCDs and a $120 price tag. However, a student member of a popular graphing calculator hacking site has leaked pictures and details about a new color-screen TI-84+ calculator, verified to be coming soon from Texas Instruments. With the lukewarm reception to TI's Nspire line, it seems to be an attempt to compete with Casio's popular color-screen Prizm calculator. Imagine the graphs (and games!) on this new 320x240 canvas."
Apple users have access to PCalc on both OS X and iOS, which is the best "traditional-style" calculator app I've found, and it has RPN support. It's a freemium calculator; basic functionality is there, as well as standard "scientific calculator" features (and basic RPN, but no visual stack), but you have to pay a dollar here and there to unlock everything.
Now for an aside. I first learned of RPN in an algorithms class I took a while back, and never saw the purpose for it beyond novelty use. However, a couple weeks ago, I decided to give it a fair shot. I find that I actually like it quite a bit, but the odd thing is I can't articulate why. So I ask: Why do you, Slashdot users, like RPN?
If you can't convince them, convict them.
