"I do use a Wacom tablet for Photoshop editing, and the Astropad+iPad combo
is better in pretty much every way. Best of all, the founders have hinted
that they might bring the underlying mirroring technology, dubbed 'Liquid',
into something that would let you use an iPad as a second monitor, rather
than plain mirroring.
The only problem as it currently stands is the price: $US50 (or $US20 for
students), which happily makes it the most expensive app I've ever
considered buying. However, there is a seven-day free trial"
