The Samsung Galaxy S3 was inevitably the star of the show, but the Korean mobile-makers also took the opportunity to announce a few more extras during its London based event.

While you check out our Samsung Galaxy S3 hands-on review and try to decide whether you should be upgrading to the new Galaxy smartphone, here's our round-up of the Samsung Galaxy S3 accessories you might also want to get the wallet out for.

Samsung S Pebble

Clearly aimed at rivalling Apple’s iPod Shuffle, the S Pebble MP3 player has a clip on design and packs 4Gb of storage. Targeted at fitness fiends, the pint sized music player can plug into the S3 via a cable and will support MP3, WMA, Ogg, FLAC file formats.

Scan and Match service

Well this sounds familiar doesn’t it? Set to work in conjunction with Samsung’s Music Hub which has access to 17 million songs, Scan and Match will ‘scan’ your computer for music and then story copies in the cloud. iTunes Match anyone?

S3 stylus

If the Galaxy Note has got you wanting a stylus all over again like it’s the 1980’s, the S3 will be getting its very own capacitive stylus that has an aluminium body and a 3mm rubber tip which will be optimized for the S3’s 4.8-inch Super AMOLED screen.

AllShare Cast Hub

The AllShare Cast popped up in a FCC filing recently and Samsung confirmed that the mirroring feature would be coming to the Galaxy S3. The Cast Hub hooks up to your TV or projector via HDMI to send content across devices.

Samsung Galaxy S3 audio dock

Along with a S3 desktop dock and a a cradle that can be mounted on your car dashboard, Samsung also announced a 100W audio dock that will charge up your S3 handset while you are listening to your tunes.
