No - i've seen it about and briefly tried it but stuffed it up (my fault). TBH the screen res is surprisingly fine for most things (when surfing I use the browsers 'full screen' mode) and so it's not so much of an issue for me. I should imagine it will blur a fair bit though and not be too amazing for text. You've reminded me to sit down and try it properly again - always something else to do!
