Is it important to know what channel you are operating on?
-
only for the person designing the deployment.
or the person troubleshooting problems later when three neighbors added wifi.

Why isn't zigbee used for computers?

802.15.4 (aka ZigBee) has a speed of 250 Kb/s which is SO slow. High enough to make two phone calls, but that's it. Not enough to really "do" anything. It's plenty fast to send sensor data or basic instructions, but way too slow for any computer usage.
Old 802.11b, the slowest computer wireless tech, was 11Mb/s, which is 44x faster than Zigbee and considered worthless because it is so slow. We want our wireless in the 100Mb/s+ range these days.

I wonder if there is a tool for radio hacking zigbee?

Many of the devices that use the protocol are never updated, therefor quite a large target for hacking.
The radio protocol itself I doubt is much use to "hack" (Any cheap software defined radio will be able to imitate a Zigbee device.)
