XPATH is barely cross browser (only through gigantic JavaScript libraries like Sarissa).
JSON is useful because you don't have to parse it using a clunky JavaScript DOM interface.
XML is great, but for my web apps, I appreciate the efficiency and simplicity of JSON.
Hacking has nothing to do with the "looming threat." The story is about using the infrastructure being assembled to make the widescale use of RFID systems possible for other purposes.
The system used by the conference identified badge holders at the door. Were attendees to think the badge magically communicated with security?
All the information that could be gathered by this RFID system is public- the system can only record when a tag moves within a proximity of a reader. Given the limited read distance of contemporary readers, this information could more effectively be gathered by hiring people to write down the names of attendees as they enter a room.
RFID is an extremely useful technology in broad use today. Imagine the backlash when the public finds out millions of automobiles are "bugged" with RFID tags (the E-Z Pass system.) This article irresponsibly suggests that RFID inherently threatens privacy.
I swear by it...
The joys of a cordless keyboard and such are not that one can sit ten feet away and still compute, rather that things dont get all tangled up.
The wireless products also are very useful when working with another person at a single computer- passing is effortless.
The logitech mouse is a bit odd though. A little too large I think. Overall very good.
