MacWorld.co.uk has reported on research findings from iSuppli which suggest 20% of portable media players will be Wifi enabled by 2012. The ability to sync, download and stream wirelessly is going to be an increasingly key function of media players, moreso even than other technologies such as touch screen or bluetooth.
One company that has long been pioneering integrated Wifi on media players is Archos, and not one to rest on their laurels when it comes to innovation, they have just announced the release of a "GPS In Car Holder" add on for their popular 605 media player. This brings satellite navigation mapping together with the Archos screen and audio quality to create the ultimate entertainment and navigation device.
I hope to be able to review at some point in the future so come back soon for more info.
