1:00 PM -- BlackBerry CEO Thorston Heins addressed a packed house at BlackBerry World Tuesday in Orlando, but the pressure on the new CEO was so palpable I could feel it through my computer over 1,000 miles away.

OK, I'm being dramatic. But, RIM's current market situation is pretty dramatic. The one-time smartphone leader and enterprise king has fallen from grace -- and fast. It's pinning all its hopes of recovery on BlackBerry 10, which it unveiled Tuesday.

That said, what it showed off today was pretty impressive. There was no hardware, save for a prototype -- disappointing, but not surprising -- but the keyboard, the camera, the user interface and even a few of the app demos were noteworthy.

I was, however, hoping for examples of how RIM is taking advantage of Long Term Evolution (LTE) -– how the BlackBerry 10 devices would showcase its power for the enterprise and how apps could tap into the fast data network.

Heins did promise that BlackBerry 10 would be fast and more efficient when it came to battery and data use, but didn't specifically address how they're made for the LTE network, an important consideration since they're (hypothetically) launching around the same time. I also foresee some challenges for the handset maker, which designed its UI to have apps constantly running while also promising stellar data efficiency.

That said, the BlackBerry 10 preview today was a good start, but it's only the start -- and right now it's all talk. The prototype device, the new specs and the software itself are all still in the development stages. RIM needs to make good on its promises and not waste any more time.

I'm not alone in wanting to see more action. The developers, wireless operators, enterprises and consumers are counting on it. That is, if they haven't already counted RIM out.
