While the Go sales on their own are quite low, combined PSP sales are above DS so the platform as a whole is doing just fine.
Plus, it is selling better than 360, which counts for something.
If anyone was expecting the DL only concept to do massive numbers they were delusional. However, it is an expanding market and here to stay. Better to get in early and have a hand in how it develops.
