Upgrading other tech

Old dSLRs
Some new dSLRs support old lenses, which is particularly useful if you've bought expensive telephoto lenses for your old camera. The best way to check if a camera is backwards-compatible is either to read one of our reviews or take the lens with you to a shop before you buy your new camera.

Old MP3 players
Getting a new case or decorating your old MP3 player is one way of jazzing it up, but if you've got an iPod that's at the end of its days, you might think about using it as a portable hard drive. Many MP3 players double up as mass storage devices you can use to backup or transfer files.

Old mobile phones
Mobile phones can be upgraded in a variety of ways, including buying a new case, downloading a new ringtone or game, or most importantly buying a new battery. An old mobile phone can also make a good gift for a child or elderly relative, who's unlikely to care that its megapixel count isn't up to much. You could even get a pay as you go SIM card if the person you're giving it to doesn't have a SIM at all.
