And with 80MB of memory as standard, with the option of using external memory cards, there's an awful lot of space to store your budding masterpieces on. Yet the fun doesn't stop there - as well as an impressive collection of video features, including video recording and messaging, the D900 also stands out with its audio features. Supporting MP3 as well as AAC and AAC+, the sound is CD-quality and allows you to set up your favorite songs as the ring tone. Just be sure not to pick one that's going to annoy everyone on the Tube when your mobile phone goes off! Everyone's heard of Bluetooth now and the fun that can be had swapping files with your friends or work colleagues, and the Samsung D900 doesn't disappoint here either. It combines this with USB support as well as Pictabridge software, ensuring you not only get the best results when taking a picture, or filming, but that they're easy to share as well.
