I've had an S3 for a few weeks, but I've been too busy to use it for much more than phone, SMS and GPS. From what I've seen, it's a stunning piece of kit though. The Google Maps sat-nav on such a big screen wipes the floor with TomTom. My only problem has been syncing with Outlook. Android wants you to play in the Google ecosystem, and it's not very accommodating if you choose not to. My last phone was an HTC Trinity though (5 year old Windows Mobile 5), so I'd probably be impressed with anything vaguely current. I'd really like to co-opt it into acting as a mini monitor for my Raspberry Pi...
