I’ve got to check this out on my own printouts, it’s interesting: Color Laser Printers Tracking Everything You Print.

It’s not new, but it’s getting noticed: Jordan writes “Yahoo! News is
reporting that several printer manufacturers are now and have been for
some time embedding (nearly) invisible serial numbers in every document
you print with their color laser printers, allowing law enforcement to
track any such document back to the printer which printed it. The
technology, ostensibly created to track down money counterfeiters, was
created by Xerox about 20 years ago. A Xerox researcher says that the
number-embedding chip lies ‘way in the machine, right near the laser’
and that ’standard mischief won’t get you around it.’”

I have suddenly gotten a surge of mobile mania in the past few days. I bought a Sony Ericsson T610 a few days ago and though I really like the phone (it’s my first GPRS phone) I really wish I could have gotten something better. I will soon try and switch from pay-as-you-go to a contract with either T-Mobile or Orange, which will allow me to get much better, newer phones, plus an option to pay a fixed amount for a certain amount of GPRS usage. As it is right now, I’ve tried to use GPRS on it a bit and it really eats up money like no tomorrow. I wish we had unlimited GPRS here in the UK at a cheap rate like in the US and elsewhere
I’m thinking about getting a iPaq handheld and a WiFi access point so that I can surf wireless on the PDA. I used to do a little blog reading on my older Clie, so I think it may be OK reading websites on it, but I’m not sure. It will certainly be useful when out and about though, I can use my bluetooth phone’s GPRS connection if I can’t get WiFi access.
