Samsung Showcase 2005
The SGH-ZX10 will be Samsung's first WCDMA phone for the U.S. Since Cingular is the only U.S. carrier launching WCDMA any time soon, they are quite obviously the intended carrier. That's why the ZX10 was one of the few phones in the room where Samsung didn't try to cover up the carrier logo.
With no advanced features like Bluetooth, only a 1 megapixel camera, a stub antenna, and a monochrome external display, it hardly looks like the gee-whiz technology marvel most people might expect from a 3G phone. It's not even HSDPA - just plain old WCDMA. We also couldn't find any support for video calling, although the Samsung reps on hand couldn't confirm it wouldn't have it.

Most of the ergonomics are good, but the two shortcut keys right above the d-pad are in a very unfortunate location. Because they are immediately below the display, it is natural to mistake them for softkeys. I found myself making that mistake repeatedly while using the ZX10, and I imagine others will, as well.
But it does have a few things going for it, such as the microSD memory card slot and music player, and the size:
For a WCDMA phone, the ZX10 is impressively small and light. It's no larger than a typical GSM-only phone, and in fact, smaller than many.
Below are some screenshots from the ZX10:
The ZX10 has a fairly typical user interface (UI), but it does have one unique feature. It's one of the shortcut keys mentioned earlier, which brings up a small shortcut menu from anywhere in the interface. It seems like it was designed to be some kind of multi-tasking control, but in actuality all it seems to do is provide a few shortcuts to make certain features easier to access.
Samsung is already planning a ZX20, which several reps mentioned briefly, although of course they wouldn't go into detail. Bluetooth and HSDPA were two key features of the ZX20 that they mentioned, however.
