Desktop with 27 inch monitor.

Modular, as well. There's an iMac sitting in a box because the display went out.

I can't sit on an easy chair (or anything, for that matter) and use a laptop, or even a tablet. Too awkward. Mouse beats trackpad. I use two mice since the Apple mouse's horizontal scrolling is both a blessing and a curse. Damn finder windows wig-wag back and forth unless the columns fill the screen WHICH SHOULD BE THE DEFAULT. There was a cool applescript app that would resize the window appropriately but it quit and I can't find the source.

Trackpad will ruin your wrist. I got a mouse for the iPad with case. (which sits on a desk, actually, the top of the electronic piano)
