The Raspberry Pi is not yet contagious.
To make a Pi, I have to download the opsys image in a windows box, burn the image into a SD card, then place the card into a minty fresh new pi. Pi cannot as of yet make another pi. THIS is the sense of contagion; to reproduce itself.
For this to become a true success, it must self replicate. That is, pi's must make more pi's without assistance from other machines with other operating systems. Until then, it is vulnerable to the benign neglect of the Lords of Redmond.
BTW, my pi is sitting here with this site on it, along with CNN and weather-bug. I finally just messed and messed around with it until I got the WiFi dingle to work with the machine, and now it is a (almost) wireless pi. I still have the keyboard and mouse that came with the bundle plugged into the hub. A cheap hub in that bundle would have been very well received.
This hp screen does not play well with others, including wheezy and it's display management routines; there has GOT to be a better way to control vertical and horizontal sizes so everything is on the screen at the same time.
Now chew on this: Kids are poor. RPF is working to get lots of computers into the hands of kids to meed the future needs of society for computer savvy people. OK, so that's a rational idea. Now what about getting computers into the hands of poor people- and there's a LOT of poor people. Old folks too tend to be poor, or at least financially cautious. I added the numbers, and we can definitely get a computer into the hands of the poor with a used VGA monitor for under $120. In the UK there is the RPF; we need something here in the states to persue this sort of work.
