The only survey I got was the same as the one when I bought bought my 4C. It was all about my purchasing experience. That's great, but, where their real problem is, and they seem to be ignoring this area, is after care. Warranty work, repairs, parts ordering.
Heck, the service repair manual is written with code that was built in 2004. And only runs on Internet Explorer which has since been officially discounted. Computer language has evolved so much since then, it's a completely obsolete engine.
