We had a chance to play with Motorola’s DEFY – headed to T-Mobile USA – this past week at CTIA 2010, and it’s certainly a tough little thing.  Unlike other rugged smartphones it still gets a big display – 3.7-inches in this case – and doesn’t feel like a great block of rubber.

Meanwhile, Engadget managed to find a tank of water and promptly dunked the DEFY, only to discover that T-Mobile’s claims about the smartphone’s water-resilience are indeed accurate.  Last month we saw the DEFY hold up to a few other durability tests, which certainly suggests this is one tough phone.
