Update: 4:01pm, I got my shipment confirmation...about twenty minutes after I sent an email inquiring about the ship date. Coincidence? I think not. Let this be a lesson to everyone, "Closed mouths don't get fed."
If you pre-ordered it before 4:30 pm you should get it on the release day (8/12/10). Mine is already en route and has a delivery time for tomorrow morning. This is also my first Droid and an upgrade from a BlackBerry Storm 1.
The upgrade in memory and CPU speed is not the whole story, GPU memory speeds and I think a CPU clock speed increase as well.
My friend has a Droid 1 and I have a Droid X
His Droid with 2.1 overclocked to 1Ghz did much worse than my DX on the Quadrant score, only after he upped his clock to 2.2 and upgraded to 2.2 was he able to beat my quadrant score. When my DX gets 2.2 it should blow it out of the water.
So not only is the droid 2 much faster than an overclocked Droid 1 already, but with the 45nm chips in the droid 2 it should be able to overclock as well once completely rooted.
