FINALLY, a comic that is not horrifically crappy to break the chain of comics that are horrifically crappy. Heck, he even went all out and gave us FOUR panels! that's the first time in two weeks!
It's true: This comic contains, deep within it, a funny joke. TI graphing calculators are basically the same product, for the same price, that they have been for years. Lots of other stuff has either dropped in price or gotten better, and the ol' TI is doing its thing. There may be good reasons for it, that I don't doubt. And I suppose that inflation means that the "same" price is really a lower real price. But it still is funny when you first think about it, like TI is this pathetic thing that just hobbles along while every other company is leaping into the future.
That said, there are better ways to have done this. For one thing, there's an awful lot of text in the first two panels, and it's a little hard to read. I understand it's necessary, to show all the different specs that have changed. That's why the suggestion is simple: Make the panels bigger. Same text, larger font. problem solved.
And that last panel is not important at all. The joke is clear from the end of the third panel (to anyone who is ever going to get the joke at all, that is) and the last panels just hurts it. But the girl's line is moderately funny, so my solution here is also simple: make her joke the alt-text and scrap the stupid alt-text you gave us. (you may want to append a "zing!" to the end to show that you are just poking fun at a beloved childhood device)
Oh, what I would give to have Randall let me edit his comics...alas.
