Honestly, this is what I think will happen in a hypothetical scenario.
I have a fictional E71, walking down starbucks(tim hortons if you will)
Me: *Makes call*
Stranger: Is that the new blackberry (or a blackberry)
Me: No, it's Nokia's E71
Stranger: Oh it looks just like a blackberry.
*case closed*
I can very well see that happening, and its going to only continue because Nokia's marketing is non-existent.
I hope Nokia proves me wrong with the E71/E66 though.
