I'm wating for about one year for the availility of the Sun's SPOT (Small Programmable Object Technology) widget and development environment. Now it is available, but only for US-developers. I'm living in germany, so it is still a problem to get one for me.
SPOT is a device with sensors (accelaration, temparature), input, outputs and networking capability and very tiny VM. I hope it will be available also at JavaONE.
This is probably the coolest gadget since the Java Ring. Such things are the "Java-Difference".
