"it will soon"
Out of the box, the Curve has more features. We have to wait for developers for functionality. According to the last T-Mo rep I spoke with, who had a demo G1, ther is no Enterprise support, nor is it necessarily in the plans. As for video, you are hoping that video recording is developed. http://blogs.zdnet.com/gadgetreviews/?p=368
Camera: The G1 has 3-megapixel camera. It does not however capture video or offer zoom functionality. It does support video playback for the following formats – H.264, streaming, 3GPP, MPEG4, and Codec 3GP files. http://www.mobilecrunch.com/2008/09/22/t-mobile-g1-specs-leaked-prior-to-announcement/
