We've already gotten a pretty good idea of Ion's capabilities, but NVIDIA doesn't seem to be one to turn down an opportunity to show it off, and it did just that recently at a joint press conference with Microsoft. As you might have guessed, the pair was especially keen to show off Windows 7 multitasking on the platform and, judging from the video available at the read link below, it seems to be more than up to the task, with it able to convert a 1080p video file to a more portable size while the video was playing, and play Left 4 Dead at 720p resolution without any noticeable hiccups. In other news, NVIDIA also confirmed that the first Ion-based system would, in fact, be a desktop, and that it'll begin shipping sometime this spring. Unfortunately, there's no word as to who may be manufacturing said desktop, with NVIDIA's Drew Henry only going so far as to say that it'll be "very small" and "affordable."
