I managed to quickly test drive the Interl Compute Stick this week. Out of the box and plugged into a projector (USB wireless keyboard and mouse connected as well), we have Python installed and had a quick test run on Minecraft. I had no doubt that Python would work well but I did have some serious reservations whether Minecraft would run (it did run in fact although perhaps was a little laggy).
The fact that you can actually install applications on this little device and it connects to the internet via a WIFI connection means that it could either be a handy little emergency device OR a very very cheap desktop style device for students (these are around $150 US or £100!).
OK so you are not going to be able to run advanced CAD stuff or music applications but for normal programming needs and using Office or Google Docs, these things work right out of the box and for a very reasonable price.
An alternative is the Liva Mini PC Kit which is slightly more expensive but the fact you can wire in a LAN connection and the fact that is has more ports would mean this would be my choice and could mean it's a viable choice for schools.
We already have the possibility of a Computer on a Chip which is a $9 device (can things get too small?) and all of a sudden we could have very inexpensive Computer labs and this could reopen the case for maintaining a dedicated space for computing (like we have for drama and music and many many other subjects) and I think there is a big argument for having a dedicated space for computing (lab or not) which will have to be a future post.
