Samsung's d807 ultraslim slider

Samsung has obviously been able to garner a rather positive reaction to their t809 ultrathin slider, and -- one good turn deserving another -- has announced the t807, an even thinner (14.9mm) slider. This one will also feature a 1.3 megapixel camera, MicroSD slot, Bluetooth, and stereo speakers. Expect the d807 sometime in the second quarter.
















Is it d807 or t807 and why is everyone using microSD and not miniSD? MiniSD isn't that much bigger and it has higher capacity and is cheaper.
So how is this different from the t809 and who will be picking it up?
Dang, I already purchased the t809!
Hope the reception is better than the t809. That one was a big disappointment to me.
