The biggest issue is that a lot of low power/tablet type CPUs have crept into the mainstream inventories for laptops and desktops.
If a customer wants a cheap laptop or desktop I now have to check if that Celeron/Pentium/Athlon is a proper desktop part or just a re-badged ultra low power Atom type.
It's actually better value/simpler to buy second hand ex. corporate clearance in a lot of cases. You know what you are getting with a 3GHz C2D.
