I'm on Verizon with the 8703e and frankly love the device. Depending on who you ask, the timing for the 8800 or some variant of it for VZW is looking like Q307. What you decide to do really depends on what you want the device for. On Cingular, the 8800 will have multimedia capabilities, QWERTY keyboard and a memory slot, but no camera. Also, it will have a trackball instead of the trackwheel. I don't know how much of this will apply to the VZW model when it comes out.
