In the center ring, weighing in at less than half of a pound, we have the reigning champion of modern tech: the smartphone! And surrounding the champ, well, just a bunch of antiquated “tech” who've been kicked to the curb by this pocket-sized powerhouse. Ladies and gentlemen, it's time for a Phone Fight! Let's count how many pieces of hardware have been made obsolete by the almighty smartphone.

1. Alarm Clock: Remember when we used to rely on those annoying beeping contraptions? Now, our phones gently wake us up with the soothing sounds of chirping birds or blaring sirens. Take that, alarm clocks!

2. Camera: Who needs a fancy DSLR when your smartphone can capture Instagram-worthy pics of your avocado toast?

3. Calculator: Admit it, you haven't touched a calculator since you discovered the joys of the calculator app.

4. Flashlight: No need to fumble around in the dark for that pesky light switch; just use your smartphone's flashlight feature. It's like having a tiny lighthouse in your pocket.

5. GPS: Goodbye, paper maps! Your smartphone knows every street, coffee shop, and dog park in town.

6. MP3 Player: Dust off that old iPod and put it in a museum because your smartphone plays your favorite tunes, podcasts, and cat videos, all in one place.

7. Landline Phone: Grandma's rotary phone? Sorry, it's now just a retro decoration gathering dust.

8. Calendar: Sticky notes and paper planners are so last century. Your smartphone keeps your schedule in check.

9. Watch: Why wear a clunky wristwatch when your phone can tell you the time, your heart rate, and even the weather forecast?

10. Wallet: Cash? Credit cards? Nah, just tap your smartphone to pay for that latte and leave your wallet at home.

11. Encyclopedia: Remember those massive bookshelves filled with dusty volumes? Now you have Wikipedia at your fingertips!

12. Compass: Unless you're lost in the wilderness, your smartphone's got you covered for navigating city streets.

13. Remote Control: Your TV remote is probably buried under the couch cushions, but your smartphone can control everything from your smart TV to your thermostat.

14. Voice Recorder: Gone are the days of carrying a separate gadget for recording notes. Just whip out your phone, and it'll capture your brilliant thoughts.

15. Postcards: Why bother sending postcards when you can share travel pics instantly with everyone you know?

So, there you have it, folks! The smartphone has knocked out a slew of old-school gadgets and left them in the tech graveyard. But hey, at least now we have more room in our pockets for snacks and the ever-expanding collection of apps that rule our lives.
