… How many times have you seen someone doing a video call from a tablet? How often have you seen someone hook up a tablet to a 50-inch HDTV and use it to play HD movies and games? How many people do you know who have hooked up a keyboard to their tablet and completely ditched their laptop?

Again as is the case with photography, users can shoot, edit and post impressive videos directly from their phones. When it comes to choosing between an iPhone and point-and-shoot camera, or a flip video, the convenience of having all of those tools in one device makes the decision a no-brainer, and in so doing, you’ll also save money from having to buy several gadgets.Did Apple's iPhone Redefine Photography?

Recently, we found our Sony point-n-shoot in the back of a cabinet. Our Sony HD camcorder hasn’t been used in almost a year.

The entire movie was produced on the iPhone 4 using the Camera app and iMovie. iMovie exports video in medium (360p), large (540p), or HD (720p) format but movies uploaded to YouTube, MMS or MobileMe Gallery will be downsized to a maximum resolution of 568×320. To overcome this limitation I used another app, PixelPipe, to upload the full 720p HD video to YouTube.
