I am coming back to this thread as I think it is both important and for me topical.
I recently purchased an item from another TMO user and after around five month of hell things are in shape, I have lost over $50 on a $250 deal thanks to Paypal and he lost more and had his account frozen due to lazy incompetent Paypal staff, hopefully it will be freed up soon.

The N900 was the first mobile device to do a Bitcoin transaction, the binary is available now for command line on ARM devices.
A user friendly bitcoin wallet app with functionality with one or more of the bitcoin exchanges makes it a real way to send money internationally.

I asume those who have the option can use a web browser to do bank transfer.
