The sleek new obsidian black Treo Pro will set you back $549. It won't be available for less, in the U.S. at least, as Palm is only offering the Treo Pro unlocked, which means you can use it with T-Mobile or AT&T or any other GSM carrier of your choice, and not directly through a wireless carrier.

Palm says if you order the Treo Pro now, it'll ship on the 23rd.
