Let the hive mind of Engadget get that for you.
"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"
Ha ha ha - so they've *finally* managed to launch this over-complicated piece of junk?
Firstly, each service provider has a different way of charging - so you'll probably still get the reverse-billed text messages from most operators (although sometimes these will have the "invisible" flag set so they won't pop up a notification).
Secondly, you'll be charged WAP data rates for ploughing through the many mandated checkout pages - a charge which is anything but cheap in the UK (and I'm looking specifically at you O2...)
From a Content Provider's point of view it's also rubbish for two reasons: end users can opt-out of supplying their mobile number (there are secure intermediaries who won't pass it on) so bang goes your marketing plan. Also the charges are higher in order to cover all the infrastructure and development that had to be put in place in order to get this system.
What's easier? Texting "ring10" to 81234 or opening your WAP browser (if it's even configured) enter the WAP site address of the store, browse for the ringtone you were after, browse through the PayForIt WAP pages and finally get an SMS with a WAP Push link to the content?!
Mental, completely mental.
