After ten days without internet access, I've managed to find myself briefly on-line this afternoon - so I've been able to read all of your comments. Unfortunately I don't have time to respond to you all individually, but I do thank you all for those comments - it is nice to have some feedback!
I've also been able to see how much I've been writing. The Pocketmail is a fantastic device, but because of the size of the screen, I had no idea how much I'd been writing. The answer is: more than I thought! Just goes to show how easy it is to type on the device.
