One for the writers out there

If you have access to both a laptop and a desktop, which do you find it easier to write with?

I find myself happier writing on the iBook than I do on the iMac. It just seems a more comfortable and natural size, and it sucks my attention in a way that the iMac doesn't. Conversely, the iMac is much better for photo editing, movie editing and DVD-burning, that sort of thing.

What's your experience?
