I received my D4 a couple of weeks ago and am very happy with my choice. I had the original Droid (until it went for a swim in the ocean), then the DX for about a year and a half, and now the D4. The camera shutter is stuck closed on my DX, hence I upgraded, otherwise it still works fine. That said, the D4 is noticeably faster than my DX, as it should be, even in our 3G area. When I travel to 4G I notice the faster speed loading pages, and look forward to using it in 4G areas. I do like the slide out keyboard very much, and the backlit feature is very cool. I hesitated about this added bulk, but it is worth it. The keyboard feels good and solid under the fingers. The phone is a tad hefty, but again, I got the features I wanted and don't mind this. I like having this power-packed device for personal and business use. I purchased the car dock and enjoy this feature also, although it limits function automatically. I like the added security features and have enabled encryption. Not sure exactly how this will affect video, since decreased funtion is mentioned during activation, and would like to read more detail on the encryption features, but have not found this information anywhere, not on motorola website or other. Battery life is fine, honestly, if you do a lot on any phone you are going to eat up battery. On a couple of days of particularly heavy use, my battery went low and I had to charge before the day was up. I keep a charger in my car and a spare at the office, if I need it. The camera and video are great, I use the HDMI cable and it's awesome to view my videos and pictures and use mirror mode on our flatscreen HD TV. On the phone, the display is crisp and colorful. I am very happy with my purchase!
