5 © NOKIA 2005 Virpi Roto Zoom out? Miniature page: +Better understanding on whats there -Text too small to read when rows fit the screen width -Zooming either requires a dedicated key or a mode -In optimal case, you should be able to zoom & scroll at the same time, which is hard on a limited device
