By 2010 netbooks will have enough performance and software to be "good enough" for most people. They are small and light enough that you can throw them in a briefcase, purse or backpack instead of needing a separate piece of luggage. They actually fit on airline tray tables. With an ARM processor they can run all day on a charge. With an ARM and an eInk display they can run for weeks. With an earpiece and Skype, you (in principle) won't even need a cell phone anymore. There will still be a market for high-end machines for compute intensive applications and video games, but for most people netbooks will be "good enough". Here's an amusing take on the subject:
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
