Web connected TV's are rather the norm now, and streaming services like Netflix and Hulu make having them worthwhile if you watch a lot of old TV shows or movies.
Given the relative low quality of new TV shows on the air today, an Apple TV would have to bring much higher "eyeball stickiness" to the TV set via presently unavailable and desirable features in order for me to work up any sort of desire for one. Interactivity with the TV in the same manner as with the iPad would seem to be an obvious minimum feature set. The TV becomes a bigger iPad + TV in a way similar to how the iPhone is almost anything else + a phone.
Most higher end TV's already have various web programs built in (like netflix, hulu, etc.) so the only thing that Apple could bring to the party that would be compelling is live TV. I'm guessing that'll be tough...
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.
