No-one seems to understand the purpose of Bluetooth or Zigbee. Zigbee is designed to be low power, make once, then use until it's battery dies and for sensors. Adhoc networks for routing and low response times( I think its about 40ms instead of Bluetooth's 3seconds ish) but also low bandwidth.
It's not intended to be a Bluetooth killer. They are both great for their designed purposes. Bluetooth for rechargable peripherals and Zigbee for making a load of probes to scatter around a plant to measure temperature, humidity etc and then report back on those conditions.

Seriously though, how many people will complain that the new iWood uses wood from precious trees, when the original plastic case uses fossil fuels;) And not to mention just how horribly bad any computer is for the environment...

Time to start the office pool. Put me down for 100 complaint letters to Jobs. $20....

Remember all of the recent exploits are theoretical vulnerabilities and therefore if you have tried out any of the proof of concept code and seen or heard your Mac do anything after clicking on these demonstrations, then you must be imagining things.

Also, "all of the recent exploits" are actually just a single issue, that of URL handlers going unchecked, rather than a whole plethora of exploits as the number of recent reports might have you believe.

Imagine using Google to access the cache for Google to access the cache for Google to...AHARHGH!

Given the large number of available options reproducing another image processing tool just for Mac would be a bit liek re-inventing the wheel. Or would that be an "i-wheel". (Sorry bad joke)
