My 2 Cents:  Here is a nice little comparison between the new gPhone and iPhone.  What do you think…is it the iKilla?

After the T-Mobile G1 was announced this morning, we went over the features of the G1, compared it to other phones, and listed what was missing. But we think a lot of you are asking if this compares well to the Apple iPhone 3G, and if it’s a so-called "iPhone killer." Here’s a simple side-by-side comparison chart of the two devices, with what we think are important design and feature differences (Bear in mind that some of these features might change as new applications surface). Let us know what you think.
