you have an excellent point, that seems to have been completely overlooked, superboyac.
the "iphone", the "ipad", the "ipod". everyone knows the name even if they don't know the specific product (i'm sure there are many people that think it is a single product - that "ip...." wotsit).
who knows the names of competing products? i've heard of the "android" phone or the "google" phone and that's about it.
