If I could afford this monitor, that would talk me out of an AIO.

For those who asked, I haven't bought yet - thinking about touch laptop with pen first. Wish Lenovo continued the x230t line instead of helix line... Or that macbook air or mbp had touch screen with pen support.
When will has well bloody drop for mbp or some more lenovos? That will probably determine my next purchase while I wait for more reviews on dell aio 2720.
You might as well wait another 2 months and get a haswell iMac or get the next refresh of the xps one. If you were going to get one of these you would have gotten it already rather than just waiting. Have you even used a touchscreen desktop? Novelty feature soon becomes a rarely used feature. If you want a productive touch input drop the cash on a good Wacom tablet. Whatever PC you buy make sure it comes with windows 7 installation media so you can drop back to that after a couple of weeks of windows 8 usage
