Blackman's Law of Limiting would surely apply to three dimensional chips as it does to cells. Three dimensional chips would necessarily be very small.

What about Great Internet Mersenne Prime Search? Forgot that one too?

I think that being able to type quickly and accurately on an actual keyboard (and 10 key) is a marketable skill that would be lost if the focus went to tablets.

I installed it today. The problems I see already are that the Wiki and Forums are respectively incomplete (even for 11.2) and out of date; and the ATI and NVIDIA proprietary drivers are difficult to install. On the plus side, the open source ATI drivers for my machine were installed out of the box. The ability to set up encrypted volumes was easy using the installer. The installer is also full of features and elegant. I also like the Dolphin-Superuser mode which is absent in Kubuntu. Installation of restricted multimedia codecs, dvdcss, and flash was a one-click deal. Overall I'm impressed.
