I prefer it. Why waste screen space on words? Icons are easier to see and use less space.

The only time you need the word is the one time when you don't yet know what it does. I would much prefer to RTFM one time then save that screen space.

In my favourite UIs I don't have any buttons on screen at all, but I do have an array of buttons on my desk (all labelled with letters, but their functions change depending on context). That's not really possible with a portable device, though.
