For 20 years (ok, more, really), laptops have not been fast enough to do reasonable professional-grade photo editing using standard Adobe tools. The complexity of the algorithms being applied increases at least as fast as the processor power. So, put me down on the side of wishing they'd build a SKU that could be optimized for performance, rather than only power consumption.

(Sometimes a desktop is not practical, like on a remote photo assignment, but there is a power outlet.)
