In the post dot-com era, I find there are some new buzz words like
"nano-xxx" and "bio-xxx" are seen everywhere. In the field of sensors,
"sensor networks" or "wireless sensor networks" are also gaining a lot of
eyeball in the news.

>From the visit of Zilog and Silabs, I also see that they are as well pushing
TCP/IP for 8-bit MCUs.  I actually ask them "do you ever need an fridge
which can connected to internet?" Then they cited networked vending machines
as an application.

What is your opinion for this? I did not find too many applications for
TCP/IP for smaller MCUs. For me they are more suitable with bigger 32-bit
MCUs. Anyway the price of low end Arm-based MCUs from Atmel and Philips are
hitting US$3 mark.

I also find that Zigbee is the new buzz words for Microchip, Freescale and
Silabs. Any take on Zigbee?
