10 technologies that should be extinct (but aren't)

These obsolete technologies didn't get the memo--maybe because someone wrote it on a typewriter and faxed it to them

4. Landline Telephones

According to the latest survey from the National Center for Health Statistics, nearly 25 percent of Americans have ditched their landlines for a cell phone. Another 22 million or so Americans pay for a VoIP service like Vonage to reach out and touch. Still, that leaves well over 100 million households firmly tethered to one of Ma Bell's bastard offspring. (No doubt many of these lines are also plugged into fax machines.)

Why? Because nothing says "I've fallen and I can't get up" quite like a landline. Only 5 percent of adults age 65 or older live in wireless-only households, per the NCHS--no doubt in part because mobile E911 emergency services still aren't as reliable as calling for help from your trusty wall-mounted phone. As that population gradually moves toward that great early bird special in the sky, landlines will likely follow.

5. Turntables

CDs and MP3s were supposed to kill the long-playing album for good. Instead, vinyl LPs have clung to life longer than Abe Vigoda--and along with them, the venerable turntable. Sales of vinyl albums actually increased last year, from 1.9 million to 2.8 million, according to Nielsen SoundScan, though that's still just a drop in the bucket compared to CDs (374 million) and digital tracks (1.2 billion). These days, you can get a digital turntable that plugs into your PC and converts groove-laden tunes into digital files for carrying on your iPod. Either way, this is a good thing; life's just better when listened to at 33 and 1/3.

6. Cash Registers

Ka-ching! Despite the emergence of computerized point-of-sale systems that can automatically track inventory, identify your top-selling products and best customers, and simplify back-end accounting, thousands of retail stores still rely on what's essentially a cigar box that can do third-grade math.

"The basics of the cash register haven't changed since it was invented 127 years ago," notes Tom Greenhaw, founder of CashierLive, a company that offers Web-based point-of-sale software. "While [it] might be powered by electricity now, it still can't tell you what your store has in stock (and it never will). Computers with point-of-sale software are expensive, which is why a majority of small retailers still stick with the dying cash register. But Web technology is finally coming to eliminate the cash register."

Basic cash registers--and really, cash itself--are analog dinosaurs in the digital jungle of financial transactions. It's time for them to check out.

7. Instant Cameras

Like their distant cousins the snooty novelists, many camera buffs eschew digital for the comfort of darkrooms and the aroma of developer fluid. Even the venerable Polaroid Instant Photo is making a comeback.

The original Polaroid company filed for bankruptcy (for the second time) in 2008 and had its assets purchased in April 2009 by a private holding company. Despite that, the newly revived firm has introduced an updated version of the OneStep camera (the Polaroid PIC 300) that, yes, uses instant film. That trip down memory lane will set you back $90 for the camera--plus a steep $1 per shot. Polaroid has even hired pop diva Lady Gaga as "creative director." If Polaroid can survive Lady Gaga, it may be with us for a long, long time.

8. Disc Drives

Shiny plastic platters of all kinds--CD, DVD, even Blu-ray--are destined to eventually follow the various floppies, Zip discs, Click drives, and other portable storage media into the digital boneyard. These days, many of us get our software via downloads and our entertainment streamed to whatever device happens to be convenient. Yet discs and disc drives persist.

"You can download almost anything today and stream much of what you can't download," says Rob Enderle, principal analyst for the Enderle Group. "Flash drives have dropped substantially in price, and we don't really need more than 64GB anyway (and you can get that in an iPod). So why don't we say hasta la vista to the disk drive and finally move to something lighter, more robust, and less noisy?"

9. Cathode Ray Tubes

In the United States, the venerable 'boob tube' has all but disappeared from offices, living rooms, and retail shelves. Yet more than 90 million CRTs were sold last year, says an MIT report--almost all of them to Asia and Latin America.

Why? Because they are both durable and cheap, and--guess what?--they still offer higher-quality pictures than LCDs and plasma sets, according to the image calibration experts at DisplayMate. Also in high demand: old, discarded CRTs, because their lead-lined glass is needed for manufacturing new ones.

10. CB Radios

Though not as wildly popular as they were back when Burt Reynolds was, well, Burt Reynolds, vendors like Cobra Electronics and RadioShack still sell thousands of Citizens Band radios each year.

Geeky graybeards will remember that the first CompuServe chat forum was called "CB Simulator." From there it's easy to draw a direct line to today's chat, IM, and Twitter clients. Still, in the era of ubiquitous 24/7 communication, CB radios are a relic, argues Jim Gardner, president of marketing consultancy Strategy 180, who bought his first Cobra CB radio in 1977 (his handle is "Moonshiner").

"Although not 10-17 (urgent), my 10-20 (position) on the issue is that given that the peak of CB radios' mainstream adoption coincided with bell bottoms, disco, and orange shag carpeting, the advent of push-to-talk cell phones should have buried this icon of bad Burt Reynolds films years ago," he says. "After all, some conversations are simply better 10-21 (on the phone). 10-4, good buddy?"

Though we take exception to the "bad Burt Reynolds films" swipe (Smokey and the Bandit and Cannonball Run are minor classics), we tend to agree: It's time to bring the hammer down.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

HP OfficeJet Pro 8730

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
