Samsung's iPhone killer certainly looks like it will give Apple a run for its money. Glowing reviews of the super-slim, two-faced UpStage are coming in. It looks like the product will be better cheaper and available earlier than Apple's effort.

The phone is half an inch thick and the size of aniPod Nano.  It will go on sale on April 1 and will cost $300--or $150 with a two-year contract.

While the  the UpStage's screen is a bit small and it lacks a QWERTY keyboard, which means that it has to deal with Apple's clever, but unproven, software keyboard.

Generally reviewers felt that video and e-mail or messaging let the UpStage down a bit, but the approach the company takes to music far outclasses Apple's i Phone.
