I had two events with my quite limited adventure with hardware:
1. We accidentally flashed firmware for 300dpi printer to 200dpi one. Printer started to work in 300dpi. Even barcodes are more clear. We popped a SRAM in, and we got a 300dpi model. There was a 50% price difference between 200 and 300dpi models.
2. One of the cheapest Samsung flat TVs. What does this "somethingPVRsomething" option in service mode do? Let's check. Turns video recording on USB drive on, while these TVs with "USB recording" support are more expensive.
Do you expect manufacturers would release the code and get losses?
