As tech speeds inexorably forward, many gadgets and services will be left in heaps on the roadside. Problem is, we'll truly miss some of them.
Technology moves so quickly, that gadgets introduced today and usually obsolete within in a few years, in favour of new improved items.
But we don't necessarily think change is always a good thing. Here are 10 tech items whose days are numbered, and we're going to miss them all - though some more than others - when they're gone.
1. MP3 players
Sure, we'll still have portable devices that can play MP3s, but a few years from now they'll all be mobile phones.
Even the once-mighty iPod is no longer a growth product for Apple; in fact, iPod sales are now declining in double-digit percentages.
It probably won't be long before Apple gives up on the thing, what with the far fatter profit margin that the iPhone offers, but consumers will lose out in the bargain.
After all, wouldn't it be nice to listen to a song or two on the train without having to pay £45 a month?
2. Optical drives
Suppose that you need to install some software on several computers. You could download a copy from an FTP site, copy it to a thumb drive, and then carry that thumb drive from one computer to another, pausing at each waystation for drivers to install and for Windows to recognise the thing.
Or you could grab a labelled, archivable application CD, pop it into each computer's optical drive, and handle the task that way (assuming that they have such a drive).
And don't get us started on the agony of trying to watch a movie on your laptop without having a drive on your laptop.
3. The mouse
A funny thing happened this year. Computer manufacturers got it into their heads that people would rather lift their entire arm up off the table and draw on their screen with their fingers instead of using a touchpad or mouse as they have for the past 25 years.
Blame the iPhone, of course. Multitouch went from the next big thing to the big thing right now, all because of that blasted device - and despite the fact that a phone in your hand and a mammoth laptop on your desk have virtually nothing in common.
We'll miss the mouse (here's its history so far). What's next? Putting multitouch into a table? Wait, don't answer that.
4. Dumb phones
Your phone has a camera, a GPS device, a compass, voice control, a stock market tracker, a weather centre, a calculator, a music player, video game controls, an email management system, a web browser, an instant messaging client, a restaurant review navigator, a Twitter feed, Facebook, an e-book reader, a happy-hour locator, a virtual DJ, and a sushi identification system.
That's all great. But once in a while, we'd just like to make a phone call.
5. Digital cameras
There's nothing quite like receiving via MMS a grainy, underlit, out-of-focus, badly framed shot of your niece.
Yet more and more the phone-clutching population is abandoning stand-alone digital cameras as the device of choice for snapping occasional photos; instead they're turning to their mobile phones, which are always at the ready and are 'good enough' for sending a snap to the 'rents or posting something pithy to their blogs.
Fortunately, mobile phone cameras are getting better (some even have a flash) and though they lack the manual controls of even a basic point-and-shoot camera, you can't argue with the convenience of carrying a single gadget instead of two.
Stand-alone cameras will continue to exist, of course, but the days of the ubiquitous shooter-around-the-neck are rapidly drawing to a close.
6. Microsoft Windows
From the over-the-top marketing campaigns to the soothing default backgrounds to the dulcet start-up sounds, what's not to like about Windows? Again, don't answer that.
But mock it all you want, Windows has served lots of people reasonably well over the years.
Now the twilight of the OS is approaching, as the cloud consumes more and more of what we used to need our computers to do. From webmail to hosted apps, online conveniences have rendered full-fledged computers unnecessary for many former users, who can get by with a Linux netbook or a Mac. We'll miss you most of all, Clippy!
We hasten to say: MySpace is horrible. We certainly won't miss the gaudy wasteland that fills 99 percent of MySpace space.
Rather, we're going to miss the original idea underlying this social network - of a place where in theory you might go to find out where your favourite band is playing, listen to their latest tracks, hear a comic try out a few new jokes, and maybe keep in touch with your friends.
Instead, MySpace has become a useless (and dying) magnet for spammers, clueless preteens, and attention addicts, none of whom seem to be in on the joke. Good riddance.
8. Pay phones
Every horror movie fan knows the drill: When things get dire, there's no mobile phone signal; or if there is, the battery dies within a couple of minutes.
If only there was a system of publicly accessible telephones that accepted change and let citizens make calls from any street corner.
Alas, the telephone companies have largely dismantled the pay-phone system, though you may still find a few phones in an airport or train station.
Worst of all, the remaining pay-phone stations sit idle and ignored. Whatever happened to turning old phone kiosks into Wi-Fi hotspots?
9. Packaged media
There's nothing quite like handing little Debbie a carefully wrapped Christmas present and watching her eyes light up as she opens it to reveal... an iTunes gift card.
The death of packaged media - CDs, DVDs, laserdiscs, you name it - has turned thoughtful, recipient-focused gift-giving into a boring and perfunctory affair, about as heartfelt as slipping your grandkid a £20 note and telling him not to spend it all in one place.
And something else bothers us even more. With a digital download, you're in possession of an album or movie that has zero resale value. In the packaged media days, you could always resell unwanted media on eBay.
10. Good manners
So there you are, pouring your soul out to your best friend over a pint, and just when you hit the meat of your story, he reaches into his pocket, pulls out his mobile phone, and starts looking through his text messages and email.
Sure, he's nodding along while you relate your tragic tale... but is he really listening or just arranging a hook-up for later?
Being connected by technology means never being out of touch with anyone else... and the rise of texting makes simultaneously carrying on multiple conversations less obvious than it would be via voice.
That doesn't make it right of course, but... hey, you can keep talking while I check this message.
