I will consider buying a Samsung Galaxy tab... once the wifi-only version has been officially released to stores.
I don't need yet another data contract. In fact, what I would love to do is to bluetooth or wifi-tether a tablet device like the Galaxy tab to my existing contracted smart phone, the HTC EVO 4G. Why would I actually commit myself to another data contract? For real-world people with real-world paying jobs like myself, it's the only option that makes sense.
