I also got a look at some experimental ThinkPad concepts. One was a tiny, PDA-sized model, with a neat, flip-out keyboard; another resurrected the butterfly keyboard; and yet another had a keyboard that lifted up slightly out of its tray to reveal ports and connections along its side. Lenovo also showed off a laptop that neatly transforms into a desktop PC: the mousepad pops out and becomes a multimedia or presentation controller, the keyboard pops off and works as a standalone wireless keyboard, and you can prop up the laptop like an upside-down V to work like a display. And it also works as a tablet.
Other computer concepts included an all-in-one-style PC, but with a twist. Conventional all-in-ones tie the display to the components, so you can't really upgrade one of them separately. Lenovo's all-in-one accomodates any number of display sizes and types, and I saw it configured with a couple of different LCD panels. In addition to detachable cameras and speakers, it also had a small, circular, swivelling footprint. And it looked good from behind--one of the major shortcomings of most office PCs.
Finally, Lenovo showed me a business desktop PC with a nice suitcase design. Notable features included a big, sturdy handle, components that tidily folded out of the box, and all of the ports and connections located on top--rather than behind--the system, for easier access. Good stuff.
