This is why I still drag around my 2.6 kg ThinkPad on a daily basis, even after buying one of those ultra portables over half a year ago. In theory they sound fine, but the keyboard is too small to work on for any extended period of time, and the computing power is still quite limited since the battery life sucks so badly if you actually use it anyway. They also lack any sort of display connector typically, or it goes through the single USB port (and no hubs support this USB -> HDMI bullshit as far as I know) or god forbid WiDi which not a single projector seems to support. In the meanwhile my ThinkPad will run CAD software on battery for 4 hours and has an actual graphics card instead of a crappy on-board thing that chokes up on HD videos. enough ports for almost anything. And sure sometimes a piece of plastic breaks off the case, but at least it doesn't bend or twist constantly.
