BGR has a source at Sprint (US network) that gives Samsung Galaxy Tab contract and off-contract (SIM Free) prices.
This is not confirmed but apparently the Galaxy Tab will sell for “$399 with a 2-year agreement and $599 full retail”. This is a decent subsidy for a connected device, depending on what the monthly fee is, we are expecting Vodafone to be in the region of its netbook price points with a data only tariff of around £20/month for 1GB data.
