In case you haven't caught on yet, there's a multi-touch centric device revolution going on. Late this morning, HP entered the ring (Update: see the new TouchPad Video) and this heavyweight is out for blood and marketshare. While the latter will suffice, the point is that the market that was once Apple's alone, is about to dramatically change. HP's latest round of trademarks points to a duo-display type of unit that's on the way and they're going to provide consumers with a lot more diversity in terms of design and price points. And joking aside, even Motorola is now on the warpath. In order for Apple to Keep their edge on these competitors, they're going to have to kick things up a notch on all things touch. In a new batch of patents that have come to light, we see that Apple is focused on bringing OLED displays to iOS and other types of devices sometime in the coming months or years.
