That's not what I meant of course. What I meant is that apps on Windows tend to be a lot more "bloated"/full of features/graphics compared to the much leaner mobile apps.

Also, most devs probably build for the average performance, so say something like an old Core 2 Duo laptop, and if their app there has a 10% CPU utilization, it might have 30% CPU utilization on Atom, or more, which means on ARM chips, especially the mid-end to low-end ones, the same app will use the CPU a lot more. Apps designed for mobile are meant to use 5-10% of those ARM CPU's from day one.
