Sony has launched the ultra-portable 4GB Micro Vault Tiny - the new addition to its colourful range of USB storage media. Designed in an eye-catching purple with a stylish clip-on carrying case, the 4GB Micro Vault is designed for those on the go.

The company says that the Tiny is ideal for sharing large numbers of music, pictures and video clips, keeping access to business or personal files whilst travelling and enabling access from any computer. The pre-loaded Virtual Expander data compression software allows users to store up to three times more data than the native capacity.

The Micro Vault Tiny products are compatible with Macintosh and Windows operating systems, including the new Windows Vista.
