	Or we could convince customers to stop buying toy router's that only work under a severely limited set of circumstances and opt for devices that pack enough CPU-punch to be actually adequate for modern internet speed tiers, no? Now if the packet accelerator is jus there to help save energy for typical cases but the CPU is powerful enough to handle a modern line with all the bells and whistles customers except, then I am all for it, but if the packet accelerator is just there to paper over an anemic CPU...

Best Regards

P.S.: I ignore issues of cost for ISP supplied CPE devices here since a) most ISPs I know actually charge rent for these devices now b) should have enough volume to drive down prices even for devices that are sufficiently fast for at least the 300 - 500 Mbps class of combined up- and download....
