Microsoft's expanding Xbox Live, adding MSN Messenger compatibility to Live and bringing its great Gamertag online ID system to PCs and mobile phones.
Live Anywhere is the name of the Xbox Live system that'll come pre-installed on MSs new Windows Vista operating system. Bill Gates outlined the new evolution himself, outrageously claiming that one Gamertag will work on your 360, PC and mobile phone - and suggesting that you'll have access to all your downloaded content whether you're at home or on your mobile on the train.
Gates even outlined a utopian vision of the future of gaming, saying that you could order Xbox Live content from your phone which would then be uploaded onto your 360.
You'll be able to voice chat across systems too, with 360 and PC owners able to see and 'interact' with each other online through the all-encompassing Live Anywhere system. This could replace text messaging, with the MSN link-up letting you fire off messages to anyone, anywhere, direct to their Gamertag.
Gates demoed the system using Shadowrun, showing an Xbox 360 gamer playing - then inviting a PC-buddy to fire up his copy of the game and play across the two platforms.
