Searching for an image of Penny’s computerized book, I was delighted to come across: 16 REAL MODERN TECHNOLOGIES PREDICTED BY INSPECTOR GADGET.
While I might choose more modern analogs; like a tablet rather than a laptop. I'm still thrilled that someone actually wrote such an article. And to be fair nearly a decade ago, phones and tablets were still quite young when it was written.
Don't think I've really watched the series since the early 2000s or late 90s, about the last time I can recall the reruns being in the air back when I watched normal TV. But still bugs me that I couldn’t recall much of what Penny’s book looked like without looking it up, lol.
