It's been several days since the last Raspberry Pi comment, so perhaps it's time to dig it up again.

Am excellent board for the casual hardware/software tinkerer, and there is a book out soon, and vibrant community.

I assume your second command was meant to be recursive, which would not be a very good thing to do at all.

If not, you've not moved them just copied, apart from the root directory.
If so, congratulations. The sound no longer works on my favourite game/application.

I suspect getting that little search dog to find my music files off of c: and listing them / drag drop would be no slower, but agree, in most instances commandline will be more efficient.

Very unlikely that this link is a picture of a nano sim. It looks exactly like a semiconductor, probably some kind of micro or SoC. Too small to handle, and no obvious contacts.

Isn't it just a sim card with a lot of the plastic bits trimmed off? Not exactly rocket Science..

I disagree,

The subsidy is clawed back by the providers by (length of the contract) x (price per month). Surely it would not make a difference to the subscription income during the course of the contract, as the monthly bills are mandatory.

What it will affect is attrition after the contract finishes. With no network lock, changing providor is just a sim card away, also could affect roaming charges, if consumers opt for a local PAYG sim when on their hols/business trips.
