I received my new 24" Dell IPS monitor today! It has a handy rotation mechanism built into the stand that is perfect for illustrating in portrait mode. And in Photoshop fullscreen mode, it actually feels like I am working on a full size canvas. I just have to get used to using more of the handy cluster button features on my Intuos 4 in order to work this way efficienty.
I guess this is about as close as I will get to a Cintique for some time :)
