2006 is shaping up to be a big year in technology. The Sun announcement ripple effect will start to be felt. I suspect we will get a lot of those types of announcements from other companies. Open source will continue to put pressure on everyone. Ajax buzz is probably going to continue to grow. I would look for efforts to make the process easier via some better tooling in the popular IDEs.
Computing power will continue to go crazy. Sun's 8 core chip that consumes about the same amount of power as a light bulb is just the beginning. All of the chip makers are going that way. More and more horsepower in smaller and smaller places.
What do we need it for? SOA of course. I expect non IT technology vendors to get into the SOA business in 2006. Refrigerators are the next big SOA thing. Just imagine your home with multiple refrigerators. Of course you don't know that they are refrigerators. All you know is you have left over pizza that needs to be kept cool. You just dynamically discover the keep cool service after you eaten all you can eat. It finds the optimal refrigerator based upon your SLA and stores your pizza at is optimal goodness. No stealing that idea, its all mine.
