Comparing this to the sausage stylus being used by iPhone owners in Korea, the Bluetooth Stylus for the Galaxy Tab will provide additional functionality aside from navigation. It can undoubtedly be used for handwriting recognition for those who don't necessarily find the on-screen keyboard to be fitting for their taste, but in addition, you'll also be able to pair it between two devices. So if this might be something that appeals to you, then the existing availability of pre-orders might be something you may want to look into. Priced at $79 through UK online retailer Play, it should very well compliment the Galaxy Tab – but so will that keyboard dock too.
