I had the 32 GB ordered, and changed it later on to the 16 GB. This phone is going to have an sd card slot, which I was unaware of when first ordering (seeing 32 Gb and 16 GB models is decieving, I thought it was like the iPhone with limited storage). So, I'm going to put an old 16 GB card into my Thunderbolt and sell it on CL for whatever I can get, and use the 32 GB card from my Thunderbolt in my GS3. Saved a cool $56!!!
I don't think that much on board storage is necessary. Most of us are coming from phones with pathetic internal storage. The D1 only has 256 MB!! The Thunderbolt has 8 GB, and I've never had a problem. Those who already ordered the 32 GB might want to reconsider. To each his own, I suppose..
